Where do you want to start?

Pick one and stay with it for a few weeks. Jumping between languages is the slowest way to learn.

Start here

A six-step path from nothing to a finished project

You do not need to finish step one perfectly before moving on. Keep going and come back when something stops making sense.

  1. 01

    Learn what code actually is

    Variables, conditions and loops. These four ideas carry you through every language.

    Programming Basics
  2. 02

    Pick one first language

    Python if you want the gentlest start, JavaScript if you want things on a screen fast.

    Python
  3. 03

    Build something tiny

    A calculator, a quiz, a to-do list. Small and finished beats big and abandoned.

    Programming Projects
  4. 04

    Learn to read errors

    Error messages are instructions, not insults. This is the skill that unblocks everything.

    Debugging & Errors
  5. 05

    Set up your tools

    An editor you like, Git for saving your work, and a folder you can find again.

    Coding Tools
  6. 06

    Keep a portfolio

    Three finished projects say more than a year of half-watched tutorials.

Build something

Do not just read code. Write some.

Every project here is small enough to finish and useful enough to be worth finishing.

When it breaks

Stuck on an error?

Everyone gets stuck — experienced developers just get unstuck faster. These guides show you how to read what went wrong and what to change.
