not

not(selector) ⇒ collection
not(collection) ⇒ collection
not(function(index){ ... }) ⇒ collection

Filter the current collection to get a new collection of elements that don't match the CSS selector. If another collection is given instead of selector, return only elements not present in it. If a function is given, return only elements for which the function returns a falsy value. Inside the function, the this keyword refers to the current element.

For the opposite, see filter.
