JavaScript 03

Welcome.

What's JavaScript Objects?
JavaScript Prototypes. All JavaScript objects inherit the properties and methods from their prototype. Objects created using an object literal, or with new Object(), inherit from a prototype called Object.prototype. ... The Object.prototype is on the top of the prototype chain.


Are function objects in JavaScript?
Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function, and the function will return a value. In JavaScriptfunctions are first-class objects, because they can have properties and methods just like any other object.
