/**
|
|
* 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' }
