JavaScript course online
JavaScript is the language that brings web pages to life - it reacts to clicks, changes content, handles forms and animations. With BitWizards you learn it in the browser, because that is JavaScript’s natural environment: you write code and see the effect immediately.

What you will learn
- Variables (
let,const), types, operators and expressions. - Conditional statements and loops (
for,while). - Functions, arrays and objects.
- Console mode with code stepping plus web tasks (HTML + CSS + JS) with a live page preview.
How you learn on BitWizards
- Code stepping: you execute JavaScript line by line and see how values change - without this, loops and functions are hard to understand.
- Live preview: HTML/CSS/JS tasks instantly show how the page looks and behaves.
- Automatic checking of the result and a preview of the expected output.
JavaScript and the INF.03 exam
JavaScript is a pillar of INF.03 (a Polish vocational IT qualification) - building websites and web applications. Together with HTML and CSS it forms a complete front-end, and with PHP and SQL - a full web application.
