JavaScript examples

JavaScript is a browser-based scripting language. With JavaScript, you add behavior to the HTML documents and control the browser or change the HTML document.

The best way to learn JavaScript is to try many examples. JavaScript is also a complex programming language, it is not easy to learn JavaScript just because it is a browser language. You must practice lots of examples.

The examples are divided broadly into two categories – basic examples and object-oriented examples. The basic example demonstrates the fundamental concepts of JavaScript and object-oriented examples, you learn about object-oriented programming concepts.
