### isArrayLike Checks if the provided argument is array-like (i.e. is iterable). Check that the object is not a function or `null` and that its `length` property is a non-negative integer below `Number.MAX_SAFE_INTEGER`. ```js const isArrayLike = val => val != null && typeof val != 'function' && val.length > -1 && val.length % 1 == 0 && val.length <= Number.MAX_SAFE_INTEGER; ``` ```js isArrayLike(document.querySelector('.className')); // true isArrayLike('abc'); // true isArrayLike(null); // false ```
