# core-assert [![Build Status](https://travis-ci.org/sindresorhus/core-assert.svg?branch=master)](https://travis-ci.org/sindresorhus/core-assert)
> Node.js [`assert`](https://nodejs.org/api/assert.html) as a standalone module *([ponyfill](https://ponyfill.com))*
Useful to ensure consistency between Node.js versions as the `assert` module has changed a lot.
Lets you use the Node.js 4.0 `assert.deepStrictEqual()`/`assert.notDeepStrictEqual()` methods all the way back to Node.js 0.10.
*Issues and improvements should be done in [Node.js](https://github.com/nodejs/node/issues) first.*
## Install
```
$ npm install --save core-assert
```
## Usage
```js
var assert = require('core-assert');
assert.strictEqual('unicorn', 'unicorn');
```
