Scripting Language: JavaScript

Scripting Language:
*To display contents in the Browser.
*To add all the elements together.
*To make web-contents dynamically. Example: Java, JavaScript, VB-script, ActiveX etc.

There are two types of the Scripting language:

1.)Client side scripting:
When client makes the request, the html and all scripts will be downloaded into your browser and then the browser documents and the resultant html will be displayed in the browser. Example: JavaScript, VB-Script etc.

2.)Server side scripting:
The request processed on the server before it is handed over to the browser. It is processed on the server side and only html is return. Example: ASP, .NET, JSP etc.

JavaScript:
JavaScript was initially developed by Brendan Eich as part of the Netscape 2.0 release. The language was called LiveScript for a while in its early stage but before the final release of Netscape 2.0, the language was publicly announced as JavaScript.
The scripting language which facilitate a discipline approach to design a computer program that enhance the functionality and the appearance of webpages. The JavaScript is usually embedded directly into html pages. So JavaScript is an interpreted language. Programming language that do not need to be compiled before execution are known as interpreted language. Software that reads and executes a program written in an interpreted language is known as an interpreter. Most modern browsers contain a JavaScript interpreter.

Guidelines for JavaScript:
*JavaScript is Case-Sensitive.
*White Space (Ignores extra space)
*Break-up line code (Line with a string can be broken up with the backslash)

*How to write JavaScript:

Script in Head Section: Well the structure of the JavaScript is same as html, the script type is defined in head section as [scripttype="text/javascript"].

Script in body Section: Here again we declare [scripttype="text/javascript"] and then we include [document.write("hello")].

When a script is placed inside the head, it is ensure that the script is loaded before anyone uses it. When a script is placed in body section, it is ensure that the contents is displayed on the webpages. If the script is placed in head and body section then unlimited number of scripts can be placed in a documents.
