This is for Node 18 forward only. It should probably never be used outside my own projects. ## API ### `any(list, [predicate])` Returns true if anything in the list passes the `predicate`. The `predicate` defaults to unit (`x => x`) so, "is anything in this list truthy?" is the default. ### `applyWhen(fn, args)` Returns a promise for the application of the function call `fn` where it will apply the `args` passed (an array) but only after resolving any promises in the list first. ### `bindAll(obj)` Binds _every_ method in the obj's prototype chain to it. Every last one. ### `contains(list, value)` Returns a boolean indicating the `value`'s presence in the `list`. ### `clone(obj)` Creates a deep clone of the `obj`. ### `defaults(obj, ...defaults)` Returns a new object with missing keys backfilled from objects passed in `defaults`. Uses left-to-right ordering. Will *not* over-write values. ### `each(obj, iterator)` Executes the iterator for every key-value-pair in `obj`. Calls iterator with `value`, `key` arguments. ### `exists(value)` Shorthand for checking value against `undefined` and `null`. ### `filter(list, [predicate])` Returns list without ### `find(list, [predicate])` Returns the first item in the `list` that matches `predicate` where `predicate` defaults to unit. ### `flatten(nestedArray)` Returns single dimensional array. ### `future()` Returns a hash with `promise`, `resolve`, `reject` properties. ### `getArguments(fn)` Returns a list of the arguments contained in the function `fn`. ### `has(obj, propertyName)` Returns a boolean indicating if `obj` has a property named `propertyName`. Ignores properties set to `undefined` or `null`. ### `intersection(list1, list2)` Returns a list of the items contained in both lists. ### `last(list, [predicate])` Returns the last occurence of an item matching `predicate` where `predicate` defaults to unit. ### `lift(asyncFn)` Returns a promisified version of the Node-style async function `asyncFn`. ### `map(obj, iterator)` Returns an array based on running `iterator` against every key value pair in `obj`. Calls `iterator` with `value`, `key` argument ordering. ### `mapCall(method, map)` Takes a method that accepts a context arg and then a series of arguments that require a mapping from an incoming object. Returns a new function that takes a context argument and an object to be mapped across the rest of the arguments. ### `matches(filter)` Creates a new function that compares a value for deep equality to make comparisons simpler and repeatable. ### `melter(target, ...args)` Combines objects in the args onto the target and rebinds any `function`s to the new target. Will not work on arrow functions! (their `this` is inherited from lexical scope and cannot be set via `bind`). ### `memoize(function)` Returns a memoized instance of the function which will memoize results based on a WeakSet of arguments passed. ### `merge(...objects)` Deep merges objects provided with the latter overriding the former. ### `omit(obj, ...keys)` Returns a new version of `obj` without the `keys`. ### `noop` ### `parseFunction(fn)` Returns an object with the properties `name` and `arguments`. ### `reduce(obj, iterator, accumulator)` Returns a reduction over the key value pairs in `obj` calling `iterator`. Calls `iterator` with `accumulator`, `value`, `key` argument order. ### `sequence(...functions)` Executes the list of `functions` in order and returns a list with the ordered results. Functions can return a promise. ### `sortBy(list, identity)` Returns `list` sorted by the result returned from `identity` for each item. ### `transform(obj, aliases, [...omit])` Renames keys in `obj` using the `aliases` lookup. Will omit any key in `omit`. ### `trim(list)` Returns a new list with the space trimmed from every item. ### `trimString()` Trims space from `str`. ### `type(obj)` Returns the `obj`'s prototype name. ### `uniq(list)` Returns a unique list of values from `list`. ### `unique(list, identity)` Return a unique list of values from `list` based on the result of the `identity` function for each item. ### `values(obj)` Return the values from an Object. (like `Object.values`) ### `without(list1, list2)` Return a unique set of list1 without any of the values from list2. ### Type Tests All of the following return a boolean based on the type of the `value` passed: * `isDate(value)` * `isEqual(value)` * `isFunction(value)` * `isNumber(value)` * `isObject(value)` * `isPlainObject(value)` * `isPromisey(value)` * `isStub(value)` * `isString(value)` --- _Source: https://npm.io/package/fauxdash · Machine-readable twin of the npm.io package page.
