First steps

Install Python from python.org or use the interpreter in your terminal (python3 on Mac/Linux). For JavaScript, you only need a browser: open the developer console (F12), switch to the Console tab, and type code there. No setup required.

Start with one language and stick to it for a few weeks. Work through our Python or JavaScript examples in order: run each snippet, change a value or a variable name, and see what happens. Breaking things on purpose is one of the fastest ways to learn.

Why start with Python or JavaScript?

Python has clear syntax and a huge standard library. You can automate files, parse data, or build small tools without fighting the language. Our Python section covers strings, lists, files, and dictionaries with examples you can run in the interpreter or a script.

JavaScript runs in every modern browser and on the server with Node.js. Learning it lets you change what users see, handle clicks and forms, and later tackle full-stack apps. Our JavaScript section focuses on DOM manipulation, strings, numbers, and events.

How to practice

After you copy a snippet and run it, try a small change: use a different string, a different number, or call the function with new arguments. Then try to solve a tiny problem of your own—for example, “reverse my name” or “round my age to the nearest 10”—using the same idea. If you get stuck, compare your code to ours and see what’s different.

We don’t cover full project tutorials here; we focus on single-task solutions. For longer courses, look for structured curricula (free or paid) and use this site as a quick reference when you need a specific pattern or function.
