Learn to code by building

Codeloft Academy is a free place to learn coding by doing it. Every lesson puts a real code editor next to the explanation and checks your work the moment it runs, so you always know whether you've got it.

Why it exists

Most tutorial sites work like reference books: long menus of topics, short examples and a button that shows the answer. That's great when you already know what you're looking for, and hard when you're starting from zero. Codeloft is built around the moments beginners get stuck:

• One clear path per language, with a Continue button everywhere
• Tasks that tick themselves off when your code works
• Error messages explained in plain English, pointing to the line
• Hints that come one step at a time
• A tracer that shows C++ and C# programs running line by line

What you can learn

HTML, CSS, JavaScript, C++ and C#: 34 lessons, 2 projects, 7 code challenges and 5 quizzes. It's all free, with no account and no ads.
