for-each-plus

A better forEach.

Iterates over a list of elements, yielding each in turn to an iteratee function.

Inspired by _.forEach. 😄

Install

Install with npm

$ npm install for-each-plus

Or unpkg

<script src="https://unpkg.com/for-each-plus@1.0.3/umd/index.js" />

Check out the unit tests on CodePen.

Usage

Iterates over a list of elements, yielding each in turn to an iteratee function. The iteratee is bound to the context object, if one is passed. Each invocation of iteratee is called with three arguments: (element, index, list). If list is a JavaScript object, iteratee's arguments will be (value, key, list). Returns the list for chaining.

const forEach = require('for-each-plus');

forEach([1, 2], value => console.log(value));
// => Logs `1` then `2`.
 
forEach({ 'a': 1, 'b': 2 }, (value, key) => console.log(key));
// => Logs 'a' then 'b' (iteration order is not guaranteed).
