# What is loupe?
Loupe turns the object you give it into a string. It's similar to Node.js' `util.inspect()` function, but it works cross platform, in most modern browsers as well as Node.
## Installation
### Node.js
`loupe` is available on [npm](http://npmjs.org). To install it, type:
$ npm install loupe
### Browsers
You can also use it within the browser; install via npm and use the `loupe.js` file found within the download. For example:
```html
<script src="./node_modules/loupe/loupe.js"></script>
```
## Usage
``` js
const { inspect } = require('loupe');
```
```js
inspect({ foo: 'bar' }); // => "{ foo: 'bar' }"
inspect(1); // => '1'
inspect('foo'); // => "'foo'"
inspect([ 1, 2, 3 ]); // => '[ 1, 2, 3 ]'
inspect(/Test/g); // => '/Test/g'
// ...
```
## Tests
```bash
$ npm test
```
Coverage:
```bash
$ npm run upload-coverage
```
