16 * The opposite of `_.pick`; this method creates an object composed of the
17 * own and inherited enumerable property paths of `object` that are not omitted.
18 *
19 * **Note:** This method is considerably slower than `_.pick`.
20 *
21 * @static
22 * @since 0.1.0
23 * @memberOf _
24 * @category Object
25 * @param {Object} object The source object.
26 * @param {...(string|string[])} [paths] The property paths to omit.
27 * @returns {Object} Returns the new object.
28 * @example
29 *
30 * var object = { 'a': 1, 'b': '2', 'c': 3 };
31 *
32 * _.omit(object, ['a', 'c']);
33 * // => { 'b': '2' }
