     37 ## Usage
     38 
     39 ```javascript
     40 var Symbol = require( '@stdlib/symbol/ctor' );
     41 ```
     42 
     43 #### Symbol( \[description] )
     44 
     45 Returns a [`Symbol`][mdn-symbol] primitive.

     47 <!-- run-disable -->
     48 
     49 <!-- eslint-disable symbol-description -->
     50 
     51 ```javascript
     52 var s = Symbol();
     53 // returns <symbol>
     54 ```
     55 
     56 To aid debugging, provide a [symbol][mdn-symbol] `description`.

     58 <!-- run-disable -->
     59 
     60 ```javascript
     61 var s = Symbol( 'beep' );
     62 // returns <symbol>

     73 ## Notes
     74 
     75 -   Unlike conventional constructors, the function does **not** support the `new` keyword.
     76 -   The function is only supported in environments which support [symbols][mdn-symbol]. In non-supporting environments, the value is `undefined`.
