/**

|
* 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`.
|
|
*
|
|
* @function isEmpty
|
|
* @param {*} value The value to check.
|
|
* @returns {boolean} Returns `true` if `value` is empty, else `false`.
|
|
* @example
|
|
*
|
|
* _.isEmpty(null);
|
|
* // => true
|
|
*
|
|
* _.isEmpty(true);
|
|
* // => true
|
|
*
|
|
* _.isEmpty(1);
|
|
* // => true
|
|
*
|
|
* _.isEmpty([1, 2, 3]);
|
|
* // => false
|
|
*
|
|
* _.isEmpty({ 'a': 1 });
|
|
* // => false
