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.
