What is java script?

JavaScript is a programming language that makes your web pages interactive, this eliminates download time as it is run on the user’s computer; this is often used for polls and quizzes, The support for Java script are built in on most websites and web developer simply need to use JavaScript for the java script to be active, be aware some websites black content so all you have to do is simply enable it. The two main reasons for JavaScript is validation, for example making sure what information the user puts in is correct.

What is JQuery?

JQuery is a JavaScript library which makes it much easier to use JavaScript on your website. JQuery takes many lines of JavaScript code and compacts it into a line of code making it simpler to use this means to you have to be an expert on JavaScript to use JQuery there’s load of other frameworks but JQuery seems to be the most popular.

JQuery also simplifies HTML, CSS, AJAX, Effects and animations and Utilities.

Key Features of Java Script

Support from browser

Can be used on client side and server side

JavaScript has access to document object model it means you can change your webpage while it is running which means JavaScript to add different effect to webpages.

Functional programming language

In JavaScript a function can be assigned to variables like any other data type and gives you the ability to code in functional style.

Support for objects:

JavaScript is an object oriented language but also makes it easier to use these objects and support java script.   

Key features of JQuery

JQuery has many key features one of them being its core functionality and the way it is used, It also finds content is documents with great navigating tools which is one of the reasons why it makes it much easier to use JavaScript.

Introduction

In this report i will be comparing the advantages of client side scripting to server side scripting, describe how client side scripting can improve the user experience and lastly validating and describing how client side scripting can improve form validation.

The advantages of client side scripting to server side scripting.

Server side

Advantages

There are loads of server-side technologies that can be used when developing web 

applications.the most popular is Microsoft ASP.NET in this server side code it is written in languages like C#. Server side processing is used to connect with permanent storage like files or databases. examples of server-side processing are user validation, saving and retrieving data and navigation

Disadvantages

The disadvantages of server side processing is that it creates page post back :it can introduce processing overhead which can decrease the performance which will force the user to wait for the page to be there or created. Once it is posted back to the server, the client must wait for the server to process the request and send the page back to the client.

Client side

Advantages

The advantages of client-side is that it also uses ASP.net web applications are programming languages like C#.

Comparing to server-side  code client-side scripts are embedded on users and clients web page and processes on their internet browser, client side scripts are written in languages like JavaScipt connects with HTML and CSS when it comes to text boxes and buttons all internet browser should automatically support these languages.

More advantages include faster response times, a more interactive application, less overhead on the web server. Client-side code is perfect for when the web page needs to be changed.

Disadvantages 

There are also some disadvantages of client-side scripting are that scripting languages require more time and effort, while the client's browser will support scripting language.
