# better-assert

  Better c-style assertions using [callsite](https://github.com/visionmedia/callsite) for

  self-documenting failure messages.

## Installation

    $ npm install better-assert

## Example

 By default assertions are enabled, however the __NO_ASSERT__ environment variable 

 will deactivate them when truthy.

```js

var assert = require('better-assert');

test();

function test() {

  var user = { name: 'tobi' };

  assert('tobi' == user.name);

  assert('number' == typeof user.age);

}

AssertionError: 'number' == typeof user.age
