lodash memoize timeout

This method invokes interceptor and returns value. (boolean): Returns true if value is greater than or equal to other, else false. This method is like _.pull except that it accepts an array of values to remove.Note: Unlike _.difference, this method mutates array. As a result, we're left with little choice but to throw an error. Fills elements of array with value from start up to, but not including, end.Note: This method mutates array. I am using lodash v4. To avoid this behavior use _.forIn or _.forOwn for object iteration. (boolean): Returns true if value is undefined, else false. Creates a function that invokes func with arguments reversed. Need help with micro-memoize? If customizer returns undefined, cloning is handled by the method instead. (string): Returns the kebab cased string. Checks if predicate returns truthy for all elements of collection. Description. ( Checks if value is classified as a Set object. See _.isEqual for a list of supported value comparisons. This method is like _.forOwn except that it iterates over properties of object in the opposite order. This method is like _.get except that if the resolved value is a function it's invoked with the this binding of its parent object and its result is returned. Creates an array of the own enumerable string keyed property values of object.Note: Non-object values are coerced to objects. This method is like _.assign except that it iterates over own and inherited source properties.Note: This method mutates object. This method is like _.tap except that it returns the result of interceptor. Feed it a function, and it returns a version of that function that keeps track of inputs and outputs in the way I just described. If it doesn't, then don't memoize it. If orders is unspecified, all values are sorted in ascending order. ", "(", ")", "[", "]", "{", "}", and "|" in string. Performs a deep comparison between two values to determine if they are equivalent.Note: This method supports comparing arrays, array buffers, booleans, date objects, error objects, maps, numbers, Object objects, regexes, sets, strings, symbols, and typed arrays. The iteratee is invoked with three arguments: (value, key, object). To escape additional characters use a third-party library like he.Though the ">" character is escaped for symmetry, characters like ">" and "/" don't need escaping in HTML and have no special meaning unless they're part of a tag or unquoted attribute value. The predicate is invoked with three arguments: (value, index|key, collection).Note: This method returns true for empty collections because everything is true of elements of empty collections. (boolean): Returns true if path exists, else false. // Sort by `user` in ascending order and by `age` in descending order. 21 Oct 2018 • 1 min read. The predicate is invoked with three arguments: (value, index, array). The iteratee is invoked with four arguments:(accumulator, value, index|key, collection).Many lodash methods are guarded to work as iteratees for methods like _.reduce, _.reduceRight, and _.transform.The guarded methods are:assign, defaults, defaultsDeep, includes, merge, orderBy, and sortBy. Adds all own enumerable string keyed function properties of a source object to the destination object. Invokes the method at path of each element in collection, returning an array of the results of each invoked method. lodash memoize-one postcss postcss-sass prettier pytz query-string raf react react-ace react-dom react-loadable react-redux react-required-if react-router-dom react … If accumulator is not provided, a new object with the same [[Prototype]] will be used. Source objects are applied from left to right. I was aware of the arguments optimization disqualification when I implemented _.memoize. But statistic changes :) So, I want, for example, every 1 minute memoize cache "become rotten", were cleared, like TTL fields in mongo, for the next user request to recalculate statistics. Users starred: 263; Users forked: 7; Users watching: 263; Updated at: 2020-06-18 07:26:52; promise-utils. // Invoke `sendMail` when clicked, debouncing subsequent calls. Creates a function that is restricted to invoking func once. (string): Returns the capitalized string. This solves a major headache for us, because there's no doubt that the correct parameters are being passed to the function, and we don't have to re-define an inline function, just for the purposes of setting a timeout. That way, the filter returns exactly the same objects it did the first time it was run, as long as the input to the filter was the same. (boolean): Returns true if value is a set, else false. A safe integer can be compared and represented correctly. This method is like _.max except that it accepts iteratee which is invoked for each element in array to generate the criterion by which the value is ranked. (Array): Returns the new concatenated array. Creates an array of values by running each element in collection thru iteratee. Creates a slice of array with n elements taken from the beginning. Creates an array of numbers (positive and/or negative) progressing from start up to, but not including, end. Cache can be cleared manually or after specified timeout; Cache size can be limited on LRU basis; Optionally accepts resolvers that normalize function arguments before passing them to underlying function. dotnet add package Retyped.lodash.memoize --version 4.1.6733 For projects that support PackageReference, copy this XML node into the project file to reference the package. Gets the size of collection by returning its length for array-like values or the number of own enumerable string keyed properties for objects. This method is like _.clone except that it accepts customizer which is invoked to produce the cloned value. Creates a new array concatenating array with any additional arrays and/or values. The iteratee is invoked with three arguments: (value, index|key, collection). If customizer returns undefined, assignment is handled by the method instead. It's because every memoized function has its own cache object instance. If customizer returns undefined path creation is handled by the method instead. // => Logs 'a', 'b', then 'c' (iteration order is not guaranteed). Elements are taken until predicate returns falsey. The func is invoked with the last arguments provided to the debounced function. The arity of func may be specified if func.length is not sufficient.The _.curry.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for provided arguments.Note: This method doesn't set the "length" property of curried functions. Checks if value is in collection. A step of -1 is used if a negative start is specified without an end or step. Invokes the iteratee n times, returning an array of the results of each invocation. Padding characters are truncated if they exceed length. 2019-04-09 v1.1.3 Fixed Issue 6. // => { '3': ['one', 'two'], '5': ['three'] }, // => { 'a': { 'dir': 'left', 'code': 97 }, 'd': { 'dir': 'right', 'code': 100 } }, // => { 'left': { 'dir': 'left', 'code': 97 }, 'right': { 'dir': 'right', 'code': 100 } }, // => [16, 64] (iteration order is not guaranteed). This method is like _.mean except that it accepts iteratee which is invoked for each element in array to generate the value to be averaged. '<% _.forEach(users, function(user) { %>

  • <%- user %>
  • <% }); %>'. // => Logs 'b' then 'a' assuming `_.forOwn` logs 'a' then 'b'. An alternative to _.reduce; this method transforms object to a new accumulator object which is the result of running each of its own enumerable string keyed properties thru iteratee, with each invocation potentially mutating the accumulator object. The cost of the function you're memoizing should outweigh the memoize scaffolding. Produces a random number between the inclusive lower and upper bounds. (*): Returns the result of the invoked method. (boolean): Returns true if value is NaN, else false. The inverse of _.escape; this method converts the HTML entities &amp;, &lt;, &gt;, &quot;, and &#39; in string to their corresponding characters.Note: No other HTML entities are unescaped. (Function): Returns the new constant function. The comparator is invoked with two arguments: (arrVal, othVal). Built with JavaScript. Its creation may be customized by replacing the _.memoize.Cache constructor with one whose instances implement the Map method interface of clear, delete, get, has, and set. Checks if value is the language type of Object. This is useful as a top-level navigational ... Post Comments Pads string on the left and right sides if it's shorter than length. after the two async saves have completed. The iteratee is invoked with one argument: (value). Subsequent calls to the debounced function return the result of the last func invocation. This method is like _.flatMap except that it recursively flattens the mapped results. This method is like _.flow except that it creates a function that invokes the given functions from right to left. If start is greater than end the params are swapped to support negative ranges. Source properties that resolve to undefined are skipped if a destination value exists. This method is like _.flatMap except that it recursively flattens the mapped results up to depth times. If resolver is provided, it determines the cache key for storing the result based on the arguments provided to the memoized function. If array is empty or falsey, undefined is returned. Confused about how to use the memoize function in the Lodash library. * Subsequent calls to the debounced function return the result of the last func invocation. Iteration is stopped once predicate returns falsey. The resolver will be responsible for determining the key to use to add to and query the cache. Once a property is set, additional values of the same property are ignored.Note: This method mutates object. This method is like _.fromPairs except that it accepts two arrays, one of property identifiers and one of corresponding values. The opposite of _.before; this method creates a function that invokes func once it's called n or more times. If a setting object is given, it takes precedence over _.templateSettings values.Note: In the development build _.template utilizes sourceURLs for easier debugging.For more information on precompiling templates see lodash's custom builds documentation.For more information on Chrome extension sandboxes see Chrome's extensions documentation. Rationale. Elements are dropped until predicate returns falsey. (Array): Returns the new property path array. If end is not specified, it's set to start with start then set to 0.Note: JavaScript follows the IEEE-754 standard for resolving floating-point values which can produce unexpected results. Checks if value is likely an arguments object. The func is invoked with the this binding of the memoized function. Use _.setWith to customize path creation.Note: This method mutates object. Justin Noel. A value is object-like if it's not null and has a typeof result of "object". The iteratee is invoked with one argument: (value). Creates an array of own enumerable string keyed-value pairs for object which can be consumed by _.fromPairs. The customizer is invoked with up to six arguments: (objValue, othValue [, index|key, object, other, stack]). (RegExp): Used to detect data property values to be HTML-escaped. I always end up implementing some convoluted JavaScript inside a Handlebars helper whenever I have to render lists with any depth. Gets the element at index n of array. paket add Retyped.lodash.memoize --version 4.1.6733. Subsequent sources overwrite property assignments of previous sources.Note: This method mutates object and is loosely based on Object.assign. You have to do it one by one. The purpose of this method is to "tap into" a method chain sequence in order to modify intermediate results. Creates a function that invokes func with arguments arranged according to the specified indexes where the argument value at the first index is provided as the first argument, the argument value at the second index is provided as the second argument, and so on. There are some breaking changes! The predicate is invoked with three arguments: (value, index, array). The predicate is invoked with one argument: (value). Checks value to determine whether a default value should be returned in its place. The iteratees are invoked with one argument: (value). (boolean): Returns true if value is a safe integer, else false. Of course, here memoize is helping me. If func is a property name, the created function returns the property value for a given element. Converts string, as a whole, to upper case just like String#toUpperCase. If collection is a string, it's checked for a substring of value, otherwise SameValueZero is used for equality comparisons. The iteratee is invoked with one argument: (value). Creates a function that invokes func with partials prepended to the arguments it receives. GitHub Gist: instantly share code, notes, and snippets. The order and references of result values are determined by the first array. (Function): Returns the new memoized function. Computes number rounded down to precision. Unfortunately, this also affects packages, like babel-polyfill, which rely on core-js. The iteratee is invoked with three arguments:(value, key, object). The last characters of the truncated string are replaced with the omission string which defaults to "...". The func is invoked with the last arguments provided to the debounced function. If object contains duplicate values, subsequent values overwrite property assignments of previous values. negate & friends. (boolean): Returns true if the values are equivalent, else false. The customizer is invoked with six arguments:(objValue, srcValue, key, object, source, stack).Note: This method mutates object. Implementation is inspired by similar method from UnderscoreJS. Creates a function that returns the value at path of a given object. If array is empty or falsey, undefined is returned. (boolean): Returns true if value is a buffer, else false. Checks if predicate returns truthy for any element of collection. The iteratee is invoked with one argument: (value). Provide options to indicate whether func should be invoked on the leading and/or trailing edge of the wait timeout. This method is like _.assignIn except that it accepts customizer which is invoked to produce the assigned values. This method is like _.merge except that it accepts customizer which is invoked to produce the merged values of the destination and source properties. This method is like _.uniqBy except that it's designed and optimized for sorted arrays. Creates a function that memoizes the result of func. The heuristic for whether a section qualifies for shortcut fusion is subject to change.Chaining is supported in custom builds as long as the _#value method is directly or indirectly included in the build.In addition to lodash methods, wrappers have Array and String methods.The wrapper Array methods are:concat, join, pop, push, shift, sort, splice, and unshiftThe wrapper String methods are:replace and splitThe wrapper methods that support shortcut fusion are:at, compact, drop, dropRight, dropWhile, filter, find, findLast, head, initial, last, map, reject, reverse, slice, tail, take, takeRight, takeRightWhile, takeWhile, and toArrayThe chainable wrapper methods are:after, ary, assign, assignIn, assignInWith, assignWith, at, before, bind, bindAll, bindKey, castArray, chain, chunk, commit, compact, concat, conforms, constant, countBy, create, curry, debounce, defaults, defaultsDeep, defer, delay, difference, differenceBy, differenceWith, drop, dropRight, dropRightWhile, dropWhile, extend, extendWith, fill, filter, flatMap, flatMapDeep, flatMapDepth, flatten, flattenDeep, flattenDepth, flip, flow, flowRight, fromPairs, functions, functionsIn, groupBy, initial, intersection, intersectionBy, intersectionWith, invert, invertBy, invokeMap, iteratee, keyBy, keys, keysIn, map, mapKeys, mapValues, matches, matchesProperty, memoize, merge, mergeWith, method, methodOf, mixin, negate, nthArg, omit, omitBy, once, orderBy, over, overArgs, overEvery, overSome, partial, partialRight, partition, pick, pickBy, plant, property, propertyOf, pull, pullAll, pullAllBy, pullAllWith, pullAt, push, range, rangeRight, rearg, reject, remove, rest, reverse, sampleSize, set, setWith, shuffle, slice, sort, sortBy, splice, spread, tail, take, takeRight, takeRightWhile, takeWhile, tap, throttle, thru, toArray, toPairs, toPairsIn, toPath, toPlainObject, transform, unary, union, unionBy, unionWith, uniq, uniqBy, uniqWith, unset, unshift, unzip, unzipWith, update, updateWith, values, valuesIn, without, wrap, xor, xorBy, xorWith, zip, zipObject, zipObjectDeep, and zipWithThe wrapper methods that are not chainable by default are:add, attempt, camelCase, capitalize, ceil, clamp, clone, cloneDeep, cloneDeepWith, cloneWith, conformsTo, deburr, defaultTo, divide, each, eachRight, endsWith, eq, escape, escapeRegExp, every, find, findIndex, findKey, findLast, findLastIndex, findLastKey, first, floor, forEach, forEachRight, forIn, forInRight, forOwn, forOwnRight, get, gt, gte, has, hasIn, head, identity, includes, indexOf, inRange, invoke, isArguments, isArray, isArrayBuffer, isArrayLike, isArrayLikeObject, isBoolean, isBuffer, isDate, isElement, isEmpty, isEqual, isEqualWith, isError, isFinite, isFunction, isInteger, isLength, isMap, isMatch, isMatchWith, isNaN, isNative, isNil, isNull, isNumber, isObject, isObjectLike, isPlainObject, isRegExp, isSafeInteger, isSet, isString, isUndefined, isTypedArray, isWeakMap, isWeakSet, join, kebabCase, last, lastIndexOf, lowerCase, lowerFirst, lt, lte, max, maxBy, mean, meanBy, min, minBy, multiply, noConflict, noop, now, nth, pad, padEnd, padStart, parseInt, pop, random, reduce, reduceRight, repeat, result, round, runInContext, sample, shift, size, snakeCase, some, sortedIndex, sortedIndexBy, sortedLastIndex, sortedLastIndexBy, startCase, startsWith, stubArray, stubFalse, stubObject, stubString, stubTrue, subtract, sum, sumBy, template, times, toFinite, toInteger, toJSON, toLength, toLower, toNumber, toSafeInteger, toString, toUpper, trim, trimEnd, trimStart, truncate, unescape, uniqueId, upperCase, upperFirst, value, and words.
