Installation
---
```bash
npm install assert-polyfill --save
```

Why?
---
NodeJS v0 `deepStrictEqual`/`notDeepStrictEqual` is unavailable.

```js
var assert = require('power-assert');
assert.deepStrictEqual(['foo'], ['foo'])
// TypeError: undefined is not a function

assert.notDeepStrictEqual(['foo'], ['bar'])
// TypeError: undefined is not a function
```

if above function is `undefined`, `assert-polyfill` defines the polyfill functions.

```js
require('assert-polyfill');
var assert = require('power-assert');
assert.deepStrictEqual(['foo'], ['foo']) // pass
assert.notDeepStrictEqual(['foo'], ['bar']) // pass
```

even if `--require` in [mocha](https://mochajs.org/), it is similar.

```bash
mocha --require assert-polyfill
```

Development
---
Requirement global
* NodeJS v0.12.13
* Npm v2.15.0
