JavaScript Overview and Syntax

After completing this module, you are expected to: 

• Know the keywords in JavaScript 
• Incorporate/embed JavaScript inside the HTML documents

          Based on your learnings in the past quarters, HTML wasn’t initially supposed to control the display of web pages in a browser. Web pages were static when HTML was first created, which means they could not change or alter after being rendered by the browser. However, people started to understand that greater interactivity and improved graphic design would make the web more usable as the web expanded beyond a small academic and scientific community. There are more intuitively and outwardly engaging websites that are emerging as commercial applications of the internet developed. HTML on its own, are used to deliver inactive web pages. An inactive website made up of HTML will be considered to be roughly identical to a printed book; you will be able to examine it or move around in it but the content is fixed. 

          Responding to the desire for greater web page interactivity, a new web programming language is needed. JavaScript fills this need. 

          In this module, you will learn how to use JavaScript, basic syntax and the rules of JavaScript.
