Introduction

To create a typical web page you need to combine the following:

• HTML - The language for building web pages
• CSS - The language for styling web pages
• JavaScript - The language for programming web pages

JavaScript is the programming language of the Web. All modern HTML pages are using JavaScript. JavaScript is the default scripting language in all modern browsers, and in HTML5. JavaScript is probably the most popular programming language in the world. It is the language for HTML, for the Web, for computers, servers, laptops, tablets, smart phones, and more. JavaScript can change HTML Elements! – which makes it very powerful!

You use JavaScript to program the behavior of web pages. You can use JavaScript to make your web pages more dynamic, e.g.,: you can specify what happens when a user clicks on a button, etc. You can update contents on the HTML web page. You can create and use functions, create variables, if – else, etc. – just like other programming languages. You use the <script> tag to define JavaScript code within your HTML files.
