@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

var join = require('@a-2-c-2-anpm/tempora-mollitia-quo');
var assert = require('assert');

var a = [1, 1, 1];
assert.deepEqual(join(a, 'x'), '1x1x1');

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

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