# script.library

Imports a JavaScript file from the MODLR filesystem, making its functions and variables available to the process.

Call it at the top of the script, outside `pre()`, `begin()`, `data()` and `end()`, so every function can use what it imports.

```js
script.library(path)
```

## Parameters

| Parameter | Type | Description |
|---|---|---|
| `path` | `string` | The file's path, from the root of the MODLR filesystem. |

## Examples

```js
script.library('dimension-functions.js');
```

This imports `dimension-functions.js` from the root of the MODLR filesystem.
