Checks if `value` is an empty object, collection, map, or set. Objects are considered empty if they have no own enumerable string keyed properties. Array-like values such as `arguments` objects, arrays, buffers, strings, or jQuery-like collections are considered empty if they have a `length` of `0`. Similarly, maps and sets are considered empty if they have a `size` of `0`.
