Objects

Objects are the data types and built-in interfaces of the JavaScript programming language. Each variable or literal value that we work with in our script is associated with a specific type of object that we can study all of the properties/methods/events of. Developers may create custom objects to extend the language and work with class-like code structures. Developers may also prototype the built-in objects to add useful properties or methods not built into the object’s interface.

Discover the object type and constructor function of any object in a script using the typeof operator and constructor property: var myvar = "hello"; alert( typeof myvar ); alert( myvar.constructor );
