rrrfffrrr/arraywrap.js

if it's not an array, wrap it in an array. if it's already an array, do nothing.

array wrap dot js

If it's not an array, make it one:

arrayWrap(123); // => [123]
arrayWrap("yo"); // => ['yo']
arrayWrap(null); // => [null]
arrayWrap(undefined); // => [undefined]
arrayWrap(); // => []

If it's already an array, do nothing:

arrayWrap([1, 2, 3]); // => [1, 2, 3]
arrayWrap([]); // => []

var arr = [1, 2];
arrayWrap(arr) === arr; // true

To use it in Node/Browserify/Webpack:

var arrayWrap = require("arraywrap");
arrayWrap(47);

To use it in the browser:

<script src="arraywrap.js"></script>
<script>
  arrayWrap(47);
</script>

This should support environments that don't have Array.isArray (like IE8 and below).
