                      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.
