Package description

What is for-each?

The for-each npm package is a utility that allows you to iterate over elements in an array or keys in an object, applying a function to each element or key-value pair. It is a simple and straightforward package that provides a way to perform operations on collections without the need for traditional for loops.

What are for-each's main functionalities?

Array Iteration

Iterate over an array, executing a function for each element. The function receives the value, index, and the array itself.

var forEach = require('for-each');

var array = [1, 2, 3];
forEach(array, function (value, index, array) {
  console.log(value);
});

Object Iteration

Iterate over the keys of an object, executing a function for each key-value pair. The function receives the value, key, and the object itself.

var forEach = require('for-each');

var object = {a: 1, b: 2, c: 3};
forEach(object, function (value, key, object) {
  console.log(key + ': ' + value);
});

A better forEach.

Example

Like Array.prototype.forEach but works on objects.

var forEach = require("for-each")

forEach({ key: "value" }, function (value, key, object) {
    /* code */
})

As a bonus, it's also a perfectly function shim/polyfill for arrays too!

var forEach = require("for-each")

forEach([1, 2, 3], function (value, index, array) {
    /* code */
})

Installation

npm install for-each
