    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

```bash

## Usage

```javascript
var array2dtype = require( '@stdlib/wasm-base-array2dtype' );
```

#### array2dtype( array )

Returns the WebAssembly data type for a provided `array`.

```javascript
var Float64Array = require( '@stdlib/array-float64' );
var arr = new Float64Array( 10 );

var dt = array2dtype( arr );
// returns 'float64'
```

If provided an argument having "generic" or an unknown/unsupported [data type][@stdlib/array/dtypes], the function assumes that array values can be stored as double-precision floating-point numbers and returns `'float64'`.

```javascript
var dt = array2dtype( [] );
// returns 'float64'
```

## Examples

var empty = require( '@stdlib/array-empty' );
var array2dtype = require( '@stdlib/wasm-base-array2dtype' );

// Get a list of supported array data types:
var dt = dtypes();

// For each supported data type, create an array and return its WebAssembly data type...
var v;
var i;
for ( i = 0; i < dt.length; i++ ) {
    v = array2dtype( empty( 10, dt[ i ] ) );
    console.log( '%s => %s', dt[ i ], v );
