    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>

> Parse a duration string into an object.

<section class="installation">

## Installation

```bash
npm install @stdlib/time-base-parse-duration
```

</section>

<section class="usage">

## Usage

```javascript
var parseDuration = require( '@stdlib/time-base-parse-duration' );
```

#### parseDuration

Parses a duration string into an object.

```javascript
var obj = parseDuration( '1m3s10ms' );
// returns { 'days': 0, 'hours': 0, 'minutes': 1, 'seconds': 3, 'milliseconds': 10 }

obj = parseDuration( '1m3s' );
// returns { 'days': 0, 'hours': 0, 'minutes': 1, 'seconds': 3, 'milliseconds': 0 }
```

The returned object has the following properties:

-   **days**: number of days.
-   **hours**: number of hours.
-   **minutes**: number of minutes.
-   **seconds**: number of seconds.
-   **milliseconds**: number of milliseconds.

## Notes

-   A duration string is a string containing a sequence of time units. A time unit is a nonnegative integer followed by a unit identifier. The following unit identifiers are supported:

    -   `d`: days
    -   `h`: hours
    -   `m`: minutes
    -   `s`: seconds
    -   `ms`: milliseconds

    For example, the string `1m3s10ms` is a duration string containing three time units: `1m` (1 minute), `3s` (3 seconds), and `10ms` (10 milliseconds). The string `60m` is a duration string containing a single time unit: `60m` (60 minutes).

-   Duration strings are case insensitive. For example, the string `1M3S10MS` is equivalent to `1m3s10ms`.

-   If a duration string does not contain a time unit, the respective property is set to `0`.

-   An empty string is considered a valid duration string and is parsed as `0d0h0m0s0ms`.

## Examples

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

```javascript
var parseDuration = require( '@stdlib/time-base-parse-duration' );

var obj = parseDuration( '1m3s10ms' );
// returns { 'days': 0, 'hours': 0, 'minutes': 1, 'seconds': 3, 'milliseconds': 10 }

obj = parseDuration( '60m' );
// returns { 'days': 0, 'hours': 0, 'minutes': 60, 'seconds': 0, 'milliseconds': 0 }

obj = parseDuration( '2d3h' );
// returns { 'days': 2, 'hours': 3, 'minutes': 0, 'seconds': 0, 'milliseconds': 0 }

obj = parseDuration( '1M3S' );
// returns { 'days': 0, 'hours': 0, 'minutes': 1, 'seconds': 3, 'milliseconds': 0 }

obj = parseDuration( '' );
// returns { 'days': 0, 'hours': 0, 'minutes': 0, 'seconds': 0, 'milliseconds': 0 }
