JavaScript is a lightweight and dynamic computer programming
language, which is quite common in various webpages. Its implementation allows
the user to create dynamic pages using client-side script. In addition to that
it is an interpreted programming language with object-oriented abilities.

Earlier this programming language was known as LiveScript,
but later on it got changed to JavaScript. It was launched in 1995 and made its
first appearance in Netscape 2.0. 

A standard version of the core JavaScript language is defined by the specification ECMA-262. 

  • JavaScript is a interpreted and lightweight programming language
  • Specially designed to produce network-centric applications
  • Integration with JAVA and HTML
  • Open and cross-platform

One of the most common form of JavaScript is Client-side, which is the script basically engaged in or referenced by an HTML document for the code to be interpreted by the browser.

This means it provides freedom to the page to include programs that interact with the user, dynamically create HTML content and control the browser, Instead of limiting its ability till static HTML.

The JavaScript client-side mechanism has much more potential than traditional CGI server-side script. For example it allows you to verify if the user has entered a valid e-mail address.

The JavaScript code is begins its process after the submission of the form and all the entries should be valid to submit the form to the Web Server. 

JavaScript is also used to capture use-initiated events like link navigation, button clicks and all the other actions which are initiated by the user. 

  • Minimum server interaction

Before sending the page to the server you can validate user input, which ultimately saves server traffic and puts fewer loads on your server

  • Spontaneous feedback to the visitors 

If they have forgotten to enter anything then they won’t have to wait for a page reload

  • Improved interactivity

You can produce interfaces that react when the user activates them via keyboard or highlights them with a mouse

  • Rich Interface

Using JavaScript one can include sliders and drag-and-drop components to provide rich interface to its website visitors

  • For security reasons the Client-side JavaScript won’t allow reading or writing of files
  • Most of the networking applications are not compatible with JavaScript
  • JavaScript lacks multiprocessor and multi-threading capabilities
  • JavaScript doesn’t have any multi-threading or multiprocessor capabilities

One of the major advantages of JavaScript is that it doesn’t require costly development tools and one can begin with a simple text editor such as a Notepad. In addition to that one doesn’t have to buy a compiler, as it is an interpreted language inside the context of a web browser.

  • Microsoft FrontPage
