Uses of JavaScript
JavaScript works at client end, which means when JavaScript works on the system of internet user or in simple language the computer of person browsing the web sites online.
A simple difference that will clear all that confusion about client end scripting with JavaScript and server end coding with PHP, JAVA, VB/C# in ASP.Net is to display the server time on which the website is running. You can use PHP, JAVA, C#/VB code to show the server time whereas to display the time of the computer system where the site is being explored by the user, JavaScript is used.
JavaScript is used for modifying the HTML tags, generating dynamic HTML tags that is also known as DHTML, and changing the CSS styles of web page contents.
document.write('Hello World');
JavaScript can also handle the events of basic HTML form controls such as input text, select drop down, list box, textarea, check box, radio controls etc.
