@fav/type.is-array

Checks whether a value is an array or not.

"fav" is an abbreviation of "favorite" and also the acronym of "for all versions". This package is intended to support all Node.js versions and many browsers as possible. At least, this package supports Node.js >= v0.10 and major Web browsers: Chrome, Firefox, IE11, Edge, Vivaldi and Safari.

Install

To install from npm:

$ npm install --save @fav/type.is-array

NOTE: npm < 2.7.0 does not support scoped package, but old version Node.js supports it. So when you use such older npm, you should download this package from github.com, and move it in node_modules/@fav/type.is-array/ directory manually.

Usage

For Node.js:

var isArray = require('@fav/type.is-array');
isArray([1, 2, 3]); // => true
isArray.not([1, 2, 3]); // => false

For Web browsers:

<script src="fav.type.is-array.min.js"></script>
<script>
var isArray = fav.type.isArray;
isArray([1, 2, 3]); // => true
isArray.not([1, 2, 3]); // => false
</script>
