| * The opposite of `_.pick`; this method creates an object composed of the |
| * own and inherited enumerable properties of `object` that are not omitted. |
| * |
| * @static |
| * @memberOf _ |
| * @category Object |
| * @param {Object} object The source object. |
| * @param {Function|...(string|string[])} [predicate] The function invoked per |
| * iteration or property names to omit, specified as individual property |
| * names or arrays of property names. |
| * @param {*} [thisArg] The `this` binding of `predicate`. |
| * @returns {Object} Returns the new object. |
| * @example |
| * |
| * var object = { 'user': 'fred', 'age': 40 }; |
| * |
| * _.omit(object, 'age'); |
| * // => { 'user': 'fred' } |
| * |
| * _.omit(object, _.isNumber); |
| * // => { 'user': 'fred' } |
