**load.js is a micro JS lazy-loader**

Built on top of [chain.js](https://github.com/chriso/chain.js), it allows you to lazy load your JS scripts sequentially or in parallel and handle complex dependency chains.

## Example

```javascript

load('jquery.js').then('jquery-ui.js', 'jquery-ui-theme.js').then('myscript.js').thenRun(function () {

    alert('Loaded.');

});

load('underscore.js');

```

**Some things to note:**

- `then()` is an alias for the previous method in the chain

- once *jQuery* has loaded, *jquery-ui.js* and *jquery-ui-theme.js* are loaded in parallel. When both are complete, *myscript.js* is loaded

- each chain is separate, so *underscore* and *jQuery* will load in parallel

## Example 2

Load a script after a 0.5s delay

```javascript

defer(500).thenLoad('myscript2.js');

```

### Example 3

```javascript

load('myscript2.js').onError(function (err) {

    //Handle any errors here..

});

```

**For more examples of the available methods, see the [chain.js](https://github.com/chriso/chain.js) page**
