WhatJavaScript does is it lets you create functions that can manipulate and enhance those objects to make web pages more dynamic, interactive and accessible. You can add JS to a page by embedding it in the HTML file. All of the things that make up a website are known as the document object model (DOM). This includes the HTML objects, browser- and platform-related objects, and special objects built right into the JavaScript language.You’ve probably encountered this on some pages where it says “you have Javascript turned off” and then half the page doesn’t display.Javascript is also used in PDF documents, site-specific browsers, and desktop widgets

He is now the chief technology officer at Mozilla.JS was first known as “Mocha” then LiveScript then named Javascript. It was created for the Netscape Navigator browser.It really has nothing to do with “Java” which is another programming language that was more complicated and only really programmers could use it. Javascript was influenced by it, however.Javascript was easier to use and you could use it piecemeal and didn’t have to learn the whole thing. He called it the “little brother to Java”
• #5: Javascript makes a page easier to navigate. You can also customize it. Some examples of Javascript are:-pop up boxes-drop down menus/roll overs-displaying the current date and time to various users depending on where they are and what browser they are using.When you write a JavaScript function, you have to determine when it will run – such as, when a user clicks or double-clicks on a link, submits a form or hovers over an image. These are called “events” and you can respond to them using “event handlers.” You can attach an event handler to the HTML element for which you want to respond to when a specific event occurs.So, for example, when someone mouses over a section of your page, you can write the javascript so that it produces a dropdown menu.
• #6: Those spam popup boxes that you get browsing the internet or from poorly designed websites? That is javascript.You can also:-make the browser always fullscreen-disable people from being able to copy or right click-open links in a new window-prevent user from using the back button
