JavaScript is an object-based scripting language. Object-based means that JavaScript sees the existing data structure as objects. A JavaScript object is merely a thing. It's like the objects around us.
JavaScript is cross-platform. The code will run on a wide variety of computer platforms. This means that users with all kinds of computers using different kinds of operating systems are able to obtain the same results as everybody else.
JavaScript comes in different 'flavors':
JavaScript: This was the name given by Netscape, who invented it. It was first used in Netscape 2.0. This is the most popular version of the language and is what we will be learning. The current version is 1.5.
JScript: This is the scripting language invented by Microsoft to compete with JavaScript.
ECMAScript: The de facto international standard for JavaScript. This standard covers the core of the language.
