## Usage

```javascript
var stdlib = require( '@stdlib/dist-tree' );
```

#### stdlib.&lt;name&gt;

Exposes the stdlib namespace corresponding to `name`. Supported namespaces may be determined by inspecting the enumerable property list

```javascript
var objectKeys = require( '@stdib/utils/keys' );

var props = objectKeys( stdlib );
// returns [ ... ]
```

For example, to use to the [probability density function][@stdlib/stats/base/dists/normal/pdf] for a normal distribution,

```javascript
var y = stdlib.stats.base.dists.normal.pdf( 0.5, 0.0, 1.0 );
// returns <number>
```

## Notes

-   A `tree` namespace is a nested object namespace which mirrors the project's layout (e.g., [`stdlib.math.base.special.erf`][@stdlib/math/base/special/erf]).

-   This package contains distributable files for use in browser environments or as shared ("vendored") libraries in server environments. Each distributable file is a standalone [UMD][umd] bundle which, if no recognized module system is present, will expose bundle contents to the global scope.

-   Each minified bundle has a corresponding [gzip][gzip]-compressed bundle. The [gzip][gzip] compression level for each compressed bundle is `9`, which is the highest (and most optimal) compression level. Deciding between uncompressed and compressed bundles depends on the application and whether compression is handled elsewhere in the application stack (e.g., [nginx][nginx], [CDN][cdn], _et cetera_).

-   While you are **strongly** encouraged to **vendor** bundles and host with a [CDN][cdn]/provider which can provide availability **guarantees**, especially for production applications, bundles are available via [unpkg][unpkg] for quick demos, proof-of-concepts, and instructional material. For example,

    ```html
    <script type="text/javascript" src="https://unpkg.com/@stdlib/dist-tree"></script>
    ```

    Please be mindful that [unpkg][unpkg] is a free, best-effort service relying on donated infrastructure which does **not** provide **any** availability guarantees. Under **no** circumstances should you **abuse** or **misuse** the service. You have been **warned**.

-   If you intend on embedding a standalone bundle **within** another bundle, you may need to rename `require` calls within the standalone bundle **before** bundling in order to maintain scoped module resolution. For example, if you plan on using [browserify][browserify] to generate a bundle containing embedded bundles, [browserify][browserify] plugins exist to "de-require" those bundles prior to bundling.

-   The bundles in this package expose all **browser-compatible** [stdlib][stdlib] packages, **except** the following:

    -   [@stdlib/repl][@stdlib/repl]: REPL environment.
    -   [@stdlib/namespace][@stdlib/namespace]: global alias namespace.
    -   [@stdlib/datasets/*][@stdlib/datasets]: datasets.
    -   [@stdlib/tools][@stdlib/tools]: tools.
    -   [@stdlib/types][@stdlib/types]: type definitions.

    The excluded packages can significantly inflate bundle size, and, if desired, should be bundled and sourced separately.

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var stdlib = require( '@stdlib/dist-tree' );

var y = stdlib.math.base.special.erf( 0.5 );
console.log( y );
```

To include the bundle in a webpage,

```html
<script type="text/javascript" src="/path/to/@stdlib/dist-tree/build/bundle.min.js"></script>
```

If no recognized module system is present, access bundle contents via the global scope.

```html
<script type="text/javascript">
    // If no recognized module system present, exposed to global scope:
    var erf = stdlib_tree.math.base.special.erf;
    console.log( erf( 0.5 ) );
</script>
```
