Learn Essential Javascript Fundamentals - Lite

Overview

JavaScript is a programming language that can be run by all modern web browsers. It is downloaded alongside the HTML code of a webpage. Unlike HTML, which can only be used to display content, JavaScript allows web designers to add functionality and interactivity to their websites.

What you will learn

We will begin the course by learning where to write JavaScript. We will look at writing JavaScript directly inside an HTML tag, then inside of a <script> tag, and then finally in a file separate from the HTML document. We will discuss some of the reasons for using each method.

After that, we will learn about how to manipulate some basic data types. We will learn about how to do simple arithmetic, and also look at some of JavaScript's built-in mathematical capabilities. Then, we will learn about working with words and characters, using a data type known as the "string". We will also cover the Boolean type, which is a representation of True and False inside of a programming language.

Prerequisites

HTML: The student must know how to use HTML tags and attributes. Only a very basic understanding of HTML is assumed.

Google Chrome (Recommended): Google Chrome is a free web browser and it will be

used to execute all the examples in this course. Although all browsers can run JavaScript, Chrome has extensive built-in developer tools. In the course, we will be using Chrome's JavaScript console, which will allow us to run quick little examples without the need to create and edit files.

Notepad++ (Recommended): Notepad++ is a free, open-source text editor. Although JavaScript and HTML can be written using any text editor, Notepad++ is highly recommended because of features such as syntax highlighting and auto-complete.
