string.prototype.split

string.prototype.split

An ES spec-compliant String.prototype.split shim/polyfill/replacement that works as far down as ES3. There's a number of bugs in various browser versions that this package addresses.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.

Because String.prototype.split depends on a receiver (the “this” value), the main export takes the string to operate on as the first argument.

Example

var split = require('string.prototype.split');
var assert = require('assert');

assert.deepEqual(split('abc', ''), ['a', 'b', 'c']);

var split = require('string.prototype.split');
var assert = require('assert');
/* when String#split is not present */
delete String.prototype.split;
var shimmedSplit = split.shim();

assert.equal(shimmedSplit, String.prototype.split);
assert.deepEqual(shimmedSplit('abc', ''), ['a', 'b', 'c']);

var split = require('string.prototype.split');
var assert = require('assert');
/* when String#split is present */
var shimmedSplit = split.shim();

assert.equal(shimmedSplit, String.prototype.split);
assert.deepEqual(shimmedSplit('abc', ''), ['a', 'b', 'c']);
