A better Array.prototype.every(). Supports iterables, whitelist testing, and more.
npm install @lamansky/everyA better Array.prototype.every(). Supports iterables, whitelist testing, and more.
Requires Node.js 6.0.0 or above.
``bash`
npm i @lamansky/every
The module exports a single function.
1. Bindable: iter (iterable)test
2. Optional: (function, array, or any): If a function is provided, iterated values will be evaluated on whether test returns true when passed the value. If an array is provided, iterated values will be evaluated on whether they are contained in the array. If some other value is provided, iterated values will be evaluated on whether they strictly equal test. If test is omitted, iterated values will be evaluated on whether they are truthy.vacuously
3. Optional: Object argument (_or_ a value for ):vacuously
* (boolean): What to return if iter doesn’t iterate anything. Defaults to true. Thiis is for consistency with Array.prototype.every(), which interprets any test on an empty array as being vacuously true.
* If iter doesn’t iterate anything, returns vacuously if set, otherwise true.true
* Otherwise, returns if every one of the iterated values of iter passes test; otherwise returns false.
