@a-2-c-2-anpm/tempora-mollitia-quo

An ES spec-compliant Array.prototype.join shim/polyfill/replacement that works as far down as ES3.

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

Because Array.prototype.join depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.

Example

1var join = require('@a-2-c-2-anpm/tempora-mollitia-quo');
2var assert = require('assert');
3
4var a = [1, 1, 1];
5assert.deepEqual(join(a, 'x'), '1x1x1');

1var join = require('@a-2-c-2-anpm/tempora-mollitia-quo');
2var assert = require('assert');
3/* when Array#join is not present */
4delete Array.prototype.join;
5var shimmed = join.shim();
6assert.equal(shimmed, join.getPolyfill());
7assert.equal(shimmed, Array.prototype.join);
8assert.deepEqual([1, 2, 3].join('x'), join([1, 2, 3], 'x'));

1var join = require('@a-2-c-2-anpm/tempora-mollitia-quo');
2var assert = require('assert');
3/* when Array#join is present */
4var shimmed = join.shim();
5assert.equal(shimmed, Array.prototype.join);
6assert.deepEqual([1, 2, 3].join(), join([1, 2, 3]));
