JavaScript is a client side scripting language used on WebPages for a dynamic experience. It is a object oriented scripting language having first class functions and is weakly typed. The code used in JavaScript is greatly influenced from C language and Java. JavaScript first appeared on the coding platform in 1995 and the credit for its development goes to Netscape. Today billions of web applications are powered by JavaScript and more applications being built for the future are being powered by it thus giving due popularity to this language.

You need an application that will be reaching far and wide and will be used on various platforms and various browsers then JavaScript is the answer especially for the client side scripting needs. Combined with the features of ASP.NET JavaScript has been working magic for individuals all across the world in terms of development of dynamic and safe web application that will give the users a real time experience executing any queries.

Most of the tools we use in a Visual Studio environment are geared to languages targeting the Common Language Runtime. If you program in C# or Visual Basic, you’ll be assisted by Intelligence, class browsers, class diagrams, code snippets, code analysis, and a world class debugger. The menus will list refactoring commands, and unit testing is only a few keystrokes away.

With the increasing demand of more dynamic websites that cut out the lag time between the query and response JavaScript has given the tool to cut on this time gap by means of the client side scripting language. Although JavaScript is known to possess object data types but these object data types are entirely different from C# and VB Code. AS the concept of classes is almost absent in JavaScript thus we don’t have to worry much about building a template. This certainly has a disadvantage as we are not allowed to manipulate an object by adding or removing properties and methods at runtime.

There is another feather in the cap of JavaScript that can be quite beneficial while implementing it on a web application based on ASP.NET and this is JavaScript Object Notation which is a lightweight data-interchange format based on a subset of the object literal syntax. JavaScript Object Notation allows JavaScript to exchange data over the network.

Thus JavaScript individually will be considered as a failure by many in the software industry but used in conjugation with the other web development applications and codes its working wonders and no web application really pushes off without a brush of JavaScript in it.

Ybglob define all meter and solutions of website designing and development. All internet marketer and web users with Web pages that are dynamically generated from database queries. You can imagine how exciting this is for researchers gathering and reporting information over the Web and for entrepreneurs who gave catalogs full of products and services to sell over the Web. Illustrates the use of JavaScript to provide database connectivity to Web applications. In this section I have provide an overview of the different ways in which JavaScript can be used for browser and server-side Web applications.  JavaScript’s syntax is the same for both client (browser) and server programming; however the examples I will be using in this chapter mainly reflect how JavaScript relates to browser programming.

Embedding JavaScript in HTML
JavaScript statement can be included in HTML document by enclosing the statement between an opening tag, and closing tag. Within the opening tag, the language attribute is set to “javascript” to identify the script as being javascript as opposed to some other scripting language, such as Visual Basic script. The script tag is typically used as javascript statements the script tag may be placed in either the head or the body of an HTML document. In many cases, it is to place the script tag in the head of a document to ensure that all javascript definition have been made before the body of the document is displayed. You will learn more about this in the subsection.” Use of the Document Head,” later in this section. The traditional first exercise with any programming language is to write a program to display the text Hello World, This teaches to programmer to display out, a necessary feature of the most programs. The body of our example document contains a single element: a script, identified by the and tags. The opening script tag has the attribute language =”javascript “to identify the script as a javascript. The script has a single statement; documents write (“Hello World”) that write the text Hello World to the current document object. The text written by the script becomes the part of the HTML document display by the browser.
Other Language Attributes All javascript –capable browser will process javascript code if the language attribute is set to the following other values in order to limit the browser that able to process javascript code. JavaScript Used to limit execution of a script to browsers that support javascript. These browsers are Navigator3 and later Internet Explorer4 and later, Hot Java 2.0 and later and Opera 3.5and later. Javascript. Used to limit execution of a script to browsers that support to javascript 1.2. These browsers are Navigator 4 and later, Internet Explorer 4 and later Hot Java 3.0and later.  JavaScript Used to limit execution of a script to browsers that support java script1.3. The browser is limited to Navigator 4.06 and later, Internet Explorer 5.0 and later, and Hot Java3.0 and later. JavaScript

So You Want a Web App?

 

When looking for a software or website developer, some people focus on specific technologies. Unless you have a specific need for a certain technology, it is better to emphasize the need and benefits of the project. This should include business goals, features and purpose, as well as longer-term growth plans. With this information your developer should be able to match you with the right technology.

 

For example, there are many aspects of a website or rich Internet application that may include the use of Java and JavaScript. But there are also other languages such as Flash® and Silverlight™ that do better at handling images and interactivity. By focusing on a specific technology, rather than a specific result, you may not be able to achieve the results you wanted, or the result may not be as efficient and sturdy as you need.

 

To help you understand some of these technologies, this post explains two common languages: Java and JavaScript, and explains how they are often used in modern systems. I’d also like to encourage you to check out our blog last week that looks at Microsoft’s Silverlight and Adobe Flash.

Java

Java is a programming language that is designed as a “code once, run anywhere” type of language. In fact, it was originally developed for set top boxes and other hardware systems, and was designed to be hardware independent so it could work almost anywhere.

 

It has since evolved into a very powerful and diverse language that is often used in web services, especially on the backend of websites, and as the business and logic layer for applications. In many ways it is a relative to C++, Small Talk, Objective C and other languages, and it was used as a source for C#.

 

Like many other languages, Java is a compiled language. This means that all the code is prepackaged into an application, which helps catch bugs and ensure that things are working properly. This prevents many mistakes such as typos from making it through the software development process.

 

Java development is also very commonly used in enterprise system development and it handles business logic and web services very well. It is often common to see in multi-tiered enterprise systems, and is often used in the data and general business layers of complex applications.

 

Although it has the capability to create user interfaces and graphic manipulation it is rarely used for this, or other add-ons or plug-ins are used. In website development, Java also integrates fairly well with HTML and together they can be very powerful.

 

JavaScript

 

Although similar in name, Java and JavaScript are largely unrelated. JavaScript is a “scripting language” that allows websites and web pages to perform simple logic without needing to communicate back to a centralized server for every instruction. By allowing web pages to be more interactive and function quicker, JavaScript basically enabled what is called Web 2.0.

 

As a scripting language, JavaScript leaves the code open and unpackaged so that each browser can read and interpret it as they need. This helps some browsers run faster since they read and interpret the code in different ways, but it can also lead to compatibility issues.

 

The most common example of JavaScript in use is when you buy something online and you have to fill out an online form with your name, address and other information. On a basic HTML form, you push ‘submit’ and it will need to refresh the page in order to tell you if you entered anything incorrectly. However if the page uses JavaScript then the user can be notified as each field is entered.

 

Overall this lets developers write complex apps that do not need a lot of back and forth communication to a central server, which can enhance web pages, reduce network traffic,  and create a much better user experience.

 

As mentioned above, JavaScript can run into compatibility issues as each browser uses its own JavaScript engine to read and interpret the instructions. Some browsers use a standardized tool called WebKit, but many use their own JavaScript engines which make it tough for developers.

 

Compatibility can become a big problem as developers must either create unique instructions for each browser and browser version, or they must find the least common denominator (the specific code method) that will function across each browser. This often requires lengthy QA and testing to make sure everything is stable and working properly, and even minor browser updates can occasionally “break” a website.

 

To assist with this, JavaScript developers can also use libraries, which are predefined segments of code or instructions which have been previously tested and refined. Libraries such as jQuery and Microsoft’s AJAX libraries are commonly used to save time and provide increased stability. Microsoft and others generally support these libraries and maintain them to keep them up-to-date and compatible across as many browsers as possible.
