     44 
     45 Iterator [`symbol`][mdn-symbol] which specifies the default iterator for an object.
     46 
     47 ```javascript
     48 var s = typeof IteratorSymbol;
     49 // e.g., returns 'symbol'

     60 ## Notes
     61 
     62 -   The [symbol][mdn-symbol] is only supported in environments which support [symbols][mdn-symbol]. In non-supporting environments, the value is `null`.
