foreach

What is foreach?

The 'foreach' npm package provides a utility for iterating over arrays and objects in a concise and consistent manner. It allows developers to execute a function for each element in an array or each property in an object, similar to the native forEach method available on arrays in JavaScript.

What are foreach's main functionalities?

Iterating over arrays

This feature allows you to iterate over each item in an array and execute a function that has access to the item value, index, and the original array.

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

Iterating over object properties

This feature allows you to iterate over each key-value pair in an object and execute a function that has access to the value, key, and the original object.

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

Other packages similar to foreach

lodash.foreach

Lodash provides a 'foreach' function that offers similar functionality to the 'foreach' npm package. It is part of a larger utility library, which means it comes with additional utility functions that may be beneficial for more complex projects.

array-foreach

The 'array-foreach' package is a minimalistic alternative that focuses solely on array iteration. It is similar to the 'foreach' package but does not include object iteration, making it a lighter choice if only array iteration is needed.

README

foreach

Iterate over the key value pairs of either an array-like object or a dictionary like object.

API

foreach(object, function, [context])

var each = require('foreach');

each([1,2,3], function (value, key, array) {
    // value === 1, 2, 3
    // key === 0, 1, 2
    // array === [1, 2, 3]
});

each({0:1,1:2,2:3}, function (value, key, object) {
    // value === 1, 2, 3
    // key === 0, 1, 2
    // object === {0:1,1:2,2:3}
});
