arguments-to-array

arguments-to-array

Make your function arguments into an actual array

installation:

⇒ npm install arguments-to-array

arguments:

The arguments object is an Array-like object corresponding to the arguments passed to a function.

The arguments object is not an Array. It is similar to an Array, but does not have any Array properties except length. For example, it does not have the pop method. However it can be converted to a real Array:

var args = Array.prototype.slice.call(arguments);

From https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/arguments

arguments is similar to an Array due to the indexing of its values. Like an array is indexed, keys in arguments are integers with their order zero-based.

why this module:

This module (or rather this repo) aims to hold some curated information on arguments. It is helpful for JavaScript beginners who wonder why the heck arguments.forEach() is not working! Plus it is easier to remember:

var argumentsToArray = require("arguments-to-array");

function example() {
    var array = argumentsToArray(arguments);
}

Also, see this discussion on one-line modules.

possible alternatives:

lodash

If you are using lodash you need not add this module to your dependencies list. See lodash docs on _.toArray

var _ = require("lodash");

function example() {
    var array = _.toArray(arguments);
}
