In the previous classes, we have learnt to create web pages using HTML. HTML uses many tags
                  to tell the browser how to display the content on web browsers. The web pages we have learnt
                  to create were static in nature which were not interactive. We need to use another scripting
                  language along with HTML to make web pages interactive and dynamic in nature. JavaScript is
                  one of such types of scripting languages.



                            JAVASCRIPT—A SCRIPTING LANGUAGE


                  JavaScript, often abbreviated as JS, is a client-side scripting language used for enhancing
                  users’ interaction with the web page by making web pages dynamic. The meaning of
                  client-side scripting language is that the code written in JavaScript is interpreted by the web
                  browser on which the web page is running. With the help of JavaScript, we can add different
                  types of functionalities in our web pages like taking input from the user, validating the user

                  input, displaying pop-up boxes, etc.
                  Alongside HTML5 and CSS, JavaScript is one of the core languages of the World Wide Web (WWW).
                  It was developed by Brendan Eich, a Netscape Communications Corporation programmer, in

                  1995. He takes only ten days to develop the language.

                      There are about 1.7 billion websites on the Internet from which 95% websites use
                      JavaScript.                                                                         FACT




                              FEATURES OF JAVASCRIPT


                  Some of the important features of JavaScript are as follows:
                     It is used in both client-side and server-side applications.

                     It is platform independent; hence, it runs on many operating systems.

                      It is used with HTML code and run on
                    web browsers.                                            Subject: LiveScript Launch Date

                             USING JAVASCRIPT


                  JavaScript cannot run on its own because it is a scripting language, and hence, needs to be
                  embedded within an HTML code.

                  In HTML5, we can use JavaScript in two ways: internally and externally.
