    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Usage

```javascript
var chdir = require( '@stdlib/process-chdir' );
```

#### chdir( path )

Changes the current working directory to the specified `path`.

```javascript
var err = chdir( '/foo/bar' );
```

If the function encounters an error when attempting to change the working directory, the function returns an `error`; otherwise, the function returns `null`.

## Examples

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

```javascript
var cwd = require( '@stdlib/process-cwd' );
var chdir = require( '@stdlib/process-chdir' );

// Print the current working directory:
var dir = cwd();
console.log( dir );

// Change the current working directory to the directory of this file:
var err = chdir( __dirname );
if ( err ) {
    console.error( err.message );
}

// Print the current working directory:
console.log( cwd() );

// Change the current working directory back to the original directory:
err = chdir( dir );
if ( err ) {
    console.error( err.message );
}

// Print the current working directory:
console.log( cwd() );
