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:

var assign = require('object.assign').getPolyfill(); // returns native method if compliant
	/* or */
var assign = require('object.assign/polyfill')(); // returns native method if compliant

Example

var assert = require('assert');

// Multiple sources!
var target = { a: true };
var source1 = { b: true };
var source2 = { c: true };
var sourceN = { n: true };

var expected = {
	a: true,
	b: true,
	c: true,
	n: true
};

assign(target, source1, source2, sourceN);
assert.deepEqual(target, expected); // AWESOME!
var target = {
	a: true,
	b: true,
	c: true
};
var source1 = {
	c: false,
	d: false
};
var sourceN = {
	e: false
};

var assigned = assign(target, source1, sourceN);
assert.equal(target, assigned); // returns the target object
assert.deepEqual(assigned, {
	a: true,
	b: true,
	c: false,
	d: false,
	e: false
});
/* when Object.assign is not present */
delete Object.assign;
var shimmedAssign = require('object.assign').shim();
	/* or */
var shimmedAssign = require('object.assign/shim')();

assert.equal(shimmedAssign, assign);

var target = {
	a: true,
	b: true,
	c: true
};
var source = {
	c: false,
	d: false,
	e: false
};

var assigned = assign(target, source);
assert.deepEqual(Object.assign(target, source), assign(target, source));
/* when Object.assign is present */
var shimmedAssign = require('object.assign').shim();
assert.equal(shimmedAssign, Object.assign);

var target = {
	a: true,
	b: true,
	c: true
};
var source = {
	c: false,
	d: false,
	e: false
};

assert.deepEqual(Object.assign(target, source), assign(target, source));
