* Checks if `value` is array-like. A value is considered array-like if it's |
|
* not a function and has a `value.length` that's an integer greater than or |
|
* equal to `0` and less than or equal to `Number.MAX_SAFE_INTEGER`. |

|
* @param {*} value The value to check. |
|
* @returns {boolean} Returns `true` if `value` is array-like, else `false`. |
|
* @example |
|
* |
|
* _.isArrayLike([1, 2, 3]); |
|
* // => true |
|
* |
|
* _.isArrayLike(document.body.children); |

|
* _.isArrayLike('abc'); |
|
* // => true |

|
* _.isArrayLike(_.noop); |
|
