JavaScript Tutorial
Introduction
It's easy to learn, and it can be used to create many different types of games and programs. In this tutorial we will look at some basic concepts in JavaScript before moving on to more complex concepts such as variables and functions.
It's used to make websites interactive, create dynamic web pages, display data in a web page and even control your computer by sending commands to it. Press Tab to write more...
JavaScript is easy to learn.
JavaScript is a simple language. You can learn JavaScript in a few hours, and it's easy to use for making games, interactive websites and more.
It's easy to learn, so this tutorial will teach you JavaScript from basic to advanced.
JavaScript examples are included in each chapter so that you can see how they work before moving on to more complex functions and techniques.
Examples in Each Chapter
You can see the examples in each chapter by clicking on the "Examples" tab at the top of each page. These examples contain code that you can run by clicking on a button in your browser. The results are displayed in a text box and shown below each example.
The following table describes which chapters have examples available:
An online editor is a tool that allows you to edit JavaScript code and view the result.
Here's how it works:
Open your favorite browser and go to https://codefresh.com/editor/javascript/. You'll see a list of options for editing JavaScript code, like this:
Actions: Click here to add your own actions or scripts (you can also save them as files); click here to see what action you've created; click here if there's an error in your code; or click here if something isn't working right now but should be working soon.
Variables: To create variables in your editor, type var name = value into any text field (and then press Enter). To assign values directly from anywhere else on the page such as variables declared elsewhere within function definitions or strings literals defined elsewhere within expressions such as string(x) == x .
Constants: To put constants into place already defined elsewhere within functions so they don't need creating again inside those functions themselves--or sub-functions either!--just type const numValue = 5 instead!
