An Object.assign shim. Invoke its "shim" method to shim Object.assign if it is unavailable.
This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](http://www.ecma-international.org/ecma-262/6.0/#sec-object.assign). In an ES6 environment, it will also work properly with `Symbol`s.
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:
```js
var assign = require('object.assign').getPolyfill(); // returns native method if compliant
/* or */
var assign = require('object.assign/polyfill')(); // returns native method if compliant
```
## Example
```js
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!
```
```js
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
});
```
```js
/* 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));
```
```js
/* 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));
```
