===Methods===

A [[methodMethod (computer scienceprogramming)|method]] is simply a function that has been assigned to a property name of an object. Unlike many object-oriented languages, there is no distinction between a function definition and a method definition in object-related JavaScript. Rather, the distinction occurs during function calling; a function can be called as a method.

When called as a method, the standard local variable ''{{mono|this}}'' is just automatically set to the object instance to the left of the "{{mono|.}}". (There are also ''{{mono|call}}'' and ''{{mono|apply}}'' methods that can set ''{{mono|this}}'' explicitly—some packages such as [[jQuery]] do unusual things with ''{{mono|this}}''.)
