History Of JavaScript  JavaScript was introduced by ‘Brendan Eich’ in 1995.  JavaScript was developed by Netscape communication corporation.  JavaScript become an ECMA standard in 1995.  JavaScript has been adopted by all major graphical web browser.
Introduction To JavaScript  JavaScript is a dynamic computer programming language.  It is a lightweight and most commonly used as a part of webpage.  Web pages implements allow client-side to interact with the user and make dynamic pages.  JavaScript is an interpreted programming with oop capability.  JS is a open and cross platform and designed for creating network and centric application.
 Client-side JS is the most common form of the language.  The script should be included in or referenced by an HTML document for the code to be interpreted by browser.  JS client-side mechanism provides many advantages over traditional CGI server-side script.
Where Does JavaScript Fit In?  Recall:-  Client opens connection to server.  Client sends request to server.  Server sends response to client.  Client and server close connection.  Client display the response received from server and display in HTML.  Between the body tag of HTML.  Between the head tag of HTML.  In .js file(external JavaScript).
What Can JavaScript Do?  JavaScript dynamically modify an HTML page.  JavaScript can react to user input.  JavaScript can validate user input.  JavaScript can be used to create cookies.  JavaScript users interaction does not require any communication with the server.
Advantages of JavaScript?  The merits of JS are:- Less user interaction:  You can validate user input before sending the page off to the server. this saves servers traffic.  Immediate feedback to the visitors:  They don’t have to wait for a page reload to see if they have forgotten to enter something.  Increased Interactivity:  You can create interfaces that react when the user hovers over them with a mouse or activates them via keyboard.  Richer interface:  You can use JS to include such items as drag and drop components and sliders to give a rich interface to your site visitors.
JavaScript Development Tools?  Microsoft FrontPage: Microsoft developed a popular HTML editor called FrontPage. FrontPage also provides web developer with a number of JS tools to assist in the creation of interactive website.  Macromedia Dream Weaver MX: It a very popular HTML and JS editor in the professional web development crowd. It provides several handy prebuilt JS components, integrates well with database, and conform to new standers such as XHTML and XML.  Macromedia Home site 5: It is a well-liked HTML and JS editor from Macromedia that can be used manage personal website effectively.
Limitations Of JavaScript?  Demerits of JS: We can treat that JS is a full fledged programming language.  Client-side JS doesn't allow the reading or writing of files.  This has been kept for security reasons.  JS cannot be used for networking applications because there is no such support available.  JS doesn’t have any multi threading or multi processer capabilities once again ,JS is a light weight interpreted programming language. That allows you to build interactivity into otherwise static HTML pages.
Conclusion!  JavaScript is a dynamic programming language it will gives less server interaction and increased interactivity richer interface to the user. By using of JavaScript development tools user can create interactive feel good web pages.
