@crabas0npm2/laudantium-maxime-veritatis

An Object.assign shim. Invoke its "shim" method to shim Object.assign if it is unavailable.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec. In an ES6 environment, it will also work properly with Symbols.

Takes a minimum of 2 arguments: target and source. Takes a variable sized list of source arguments - at least 1, as many as you want. Throws a TypeError if the target argument is null or undefined.

Most common usage:

1var assign = require('@crabas0npm2/laudantium-maxime-veritatis').getPolyfill(); // returns native method if compliant
2	/* or */
3var assign = require('@crabas0npm2/laudantium-maxime-veritatis/polyfill')(); // returns native method if compliant

Example

1var assert = require('assert');

3// Multiple sources!
4var target = { a: true };
5var source1 = { b: true };
6var source2 = { c: true };
7var sourceN = { n: true };

9var expected = {
10	a: true,
11	b: true,
12	c: true,
13	n: true
14};
15
16assign(target, source1, source2, sourceN);
17assert.deepEqual(target, expected); // AWESOME!
