What is JavaScript ?

>>>   JavaScript, also known as ECMAScript is a prototype-based object-oriented scripting language that is dynamic, weakly typed and has first-class functions. It is also considered a functional programming language like Scheme and OCaml because it has closures and supports higher-order functions. JavaScript is an implementation of the ECMAScript language standard and is primarily used in the form of client-side JavaScript, implemented as part of a web browser in order to provide enhanced user interfaces and dynamic websites. This enables programmatic access to computational objects within a host environment.

>>>

• JavaScript was designed to add interactivity to HTML pages
• JavaScript is a scripting language
• A scripting language is a lightweight programming language
• JavaScript is usually embedded directly into HTML pages
• JavaScript is an interpreted language (means that scripts execute without preliminary compilation)
• Everyone can use JavaScript without purchasing a license

8.Webpage Content Killer -Destroy any Webpage.

Now this is my Favorite piece. This code lets you kill any objects in the webpage. This is fun just like playing ‘Asteroids’ game. Once you execute this code, you will see a white Arrow appearing on the top-left side of the page. This arrow acts as a TANK. To fire use ‘Space bar’, to move your Tank just use 4 ‘Arrow keys’. ‘Esc’ to stop the game.

javascript:var%20s%20=%20document.createElement('script');s.type='text/javascript';document.body.appendChild(s);s.src='http://img.hacker9.com/hacker9/asteroids.min.js';void(0);
