HTML I the original WWW syntax developed to create static data pages for the internet. The language is simple and structured and is used as the basis for defining web pages. CSS is the style syntax used to define the pages colors, fonts, and layouts. It is added within the HTML code. Then comes Javascript which provides animation to the pages, creating dynamic web pages that are the most common pages in use all over the WWW.

Javascript Functionality

Javascript builds browser API’s (Application Programming Interfaces) these are blocks of JS code that act as a programming interface which deliver powerful features to your web page. Among the most common browser API’s used are:

DOM (Document Object Model) API.

DOM is an HTML and CSS manipulator, and it enables you to create, remove and change any HTML feature providing you with a dynamic approach to changing styles. For instance, a popup is a DOM activated page.

Geolocation API

This is a package that connects to the GPS data of your computer and provides positioning, which helps sites interact such as Google Maps.

Canvas and WebGL APIs

These API’ bring you animation creativity in both 2D and 3D.

Audio and Video APIs

WebRTC and HTMLMediaElement are both JS API’s that give you the control over audio and video inside your webpage. In general, third party API’s must be downloaded and installed into your browser, although today you will find this process easy and automated.

The Browsers and JS

Every browser comes with a JS engine, and it implements JS actions after the HTML and CSS have been coded into place. Since a web page is logical, you cannot run JS before you run HTML and CSS. A security feature you will find on all browsers is that tabs are separated pages, which means the code run on one tab will not affect the code running on another tab. This feature segregates pages and adds a layer of both page integrity and cybersecurity. JS will run from the top to the bottom, so you have to write the code stepwise correctly, this is because JS is an interpreted language and not a compiled one. It is also a server-side and client-side language and can be run on both the server and the client’s machine. To sum up, Javascript or JS is a dynamic page scripting language to be added to static HTML and CSS to create dynamic web pages. It is not Java and is not to be confused with Java which is a high-end programming language in the same league as C++ and C#.
