JavaScript Introduction

JavaScript is a dynamic language which is used for designing the web pages on the client side. This means that users can easily see the effect of JavaScript when browsing.

Here are some other important things to note about JavaScript:

• It is case sensitive language.
• It is untyped language i.e. a variable can hold any type of value.
• // is used for comments.
• ; i used for line termination.
• JavaScript code should be added at the end i.e. just above the closing-body-tag.
• It is better to write the JavaScript code in separate file as shown in next section.
