In this article by Stoyan Stefanov, you'll learn about the prototype property of the function objects. Understanding how the prototype works is an important part of learning the JavaScript language. After all, JavaScript is classified as having a prototype-based object model. There's nothing particularly difficult about the prototype, but it is a new concept and as such may sometimes take some time to sink in. It's one of these things in JavaScript (closures are another) which, once you "get" them, they seem so obvious and make perfect sense. As with the rest of the article, you're strongly encouraged to type in and play around with the examples; this makes it much easier to learn and remember the concepts.

The following topics are discussed in this article:

* Every function has a prototype property and it contains an object
* Adding properties to the prototype object
* Using the properties added to the prototype
* The difference between own properties and properties of the prototype
* __proto__, the secret link every object keeps to its prototype
* Methods such as isPrototypeOf(), hasOwnProperty(), and propertyIsEnumerable()
