    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>

## Installation

<section class="usage">

## Usage

```javascript
var dtypeEnums = require( '@stdlib/ndarray-base-dtype-enums' );
```

#### dtypeEnums()

Returns an object mapping supported [data type][@stdlib/ndarray/dtypes] strings to enumeration constants.

```javascript
var out = dtypeEnums();
// {...}
```

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   Downstream consumers of a returned mapping should **not** rely on specific integer values (e.g., `int8 == 0`). Instead, the object should be used in an opaque manner.
-   The main purpose of this function is JavaScript and C inter-operation of ndarray objects.

## Examples

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

```javascript
var dtypeStrings = require( '@stdlib/ndarray-base-dtype-strings' );
var dtypeEnums = require( '@stdlib/ndarray-base-dtype-enums' );

var dt = dtypeStrings();
// returns [...]

var enums = dtypeEnums();
// returns {...}

var i;
for ( i = 0; i < dt.length; i++ ) {
    console.log( '%s => %d', dt[ i ], enums[ dt[ i ] ] );
}
