# isIterableLike
> Test if a value is [`iterable`][mdn-iterable-protocol]-like.
<section class="usage">
## Usage
```javascript
var isIterableLike = require( '@stdlib/assert/is-iterable-like' );
```
#### isIterableLike( value )
Tests if a `value` is [`iterable`][mdn-iterator-protocol]-like.
```javascript
var bool = isIterableLike( [] );
// returns <boolean>
bool = isIterableLike( {} );
// returns false
```
</section>

<section class="notes">
## Notes
- In order to be [iterable][mdn-iterable-protocol], an `object` must implement the `@@iterator` method, which, when called, returns an [iterator protocol-compliant object][mdn-iterator-protocol].
- An [iterator protocol-compliant object][mdn-iterator-protocol] is an `object` having a `next` method following the [iterator protocol][mdn-iterator-protocol].
- As full [iterator][mdn-iterator-protocol] compliance is **impossible** to achieve without evaluating an [iterator][mdn-iterator-protocol], this function checks **only** for interface compliance.
- In environments lacking `Symbol.iterator` support, this function always returns `false`.
