Return the description for a provided data type.
npm install @stdlib/ndarray-base-dtype-descWe 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. 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. 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. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

``bash`
npm install @stdlib/ndarray-base-dtype-desc
`javascript`
var dtypeDesc = require( '@stdlib/ndarray-base-dtype-desc' );
#### dtypeDesc( \[dtype] )
Returns the description for a specified [data type][@stdlib/ndarray/dtypes].
`javascript
var desc = dtypeDesc( 'float64' );
// returns '...'
desc = dtypeDesc( 'generic' );
// returns '...'
`
If provided an unknown or unsupported data type, the function returns null.
`javascript`
var desc = dtypeDesc( 'foobar' );
// returns null
If not provided a [data type][@stdlib/ndarray/dtypes] value, the function returns an object mapping [data type][@stdlib/ndarray/dtypes] strings to descriptions.
`javascript`
var obj = dtypeDesc();
// returns {...}
`javascript
var dtypeDesc = require( '@stdlib/ndarray-base-dtype-desc' );
var dtypes = [
'float64',
'float32',
'int8',
'uint8',
'uint8c',
'int16',

'int32',
'uint32',
'binary',
'generic',
'foobar'
];
var i;
for ( i = 0; i < dtypes.length; i++ ) {
console.log( '%s: %s', dtypes[ i ], dtypeDesc( dtypes[ i ] ) );
