Learn to code with tutorials written by people who ship software
Every lesson is built around code you run yourself, organized by skill level so you always know what to tackle next.
From your first line of code to production-ready projects
Most programming tutorials assume you already know more than you do, or they explain a concept once and move on before it sticks. Ours are built differently: each one starts with the smallest version of a problem, explains why the code works the way it does, and adds complexity a step at a time. If a term shows up before we've defined it, that's a bug in the tutorial, and we fix it once a reader points it out.
We cover programming fundamentals, JavaScript and Python, Git and version control, core web development, and the data structures and algorithms concepts that come up most often in technical interviews and everyday problem solving. New tutorials are added every month, and older ones get revisited when a language or framework changes enough to matter.
Pick a track, or work through more than one at a time
Programming Fundamentals
Variables, control flow, functions, and the vocabulary you need before any language-specific tutorial will make sense.
Web Development
HTML, CSS, and JavaScript basics, building up to simple full-stack projects you can deploy and show off.
Git & Version Control
Branching, merging, pull requests, and the habits that make working on a team, or just your own past commits, easier to manage.
Data Structures & Algorithms
Arrays, hash maps, trees, and the problem-solving patterns that show up constantly in coding interviews.
Four things every tutorial includes
Concept before code
We explain what a piece of code is supposed to accomplish before showing the code itself, so you're never copying something you don't understand.
Runnable examples
Every example is written to run as shown. If it needs a specific version of a language or tool, we say so at the top of the article.
Common mistakes, called out
We flag the errors beginners hit most often at the point they're likely to hit them, not in a separate troubleshooting section at the end.
A short practice exercise
Most tutorials end with a small variation on the problem for you to solve on your own, so the concept has a chance to stick.
Tutorials FAQ
Do I need to install anything to follow along?
Some beginner tutorials use an in-browser code editor so you can start without installing anything. Once you're working with a real project, we walk you through setting up a local environment step by step.
Are the tutorials really free?
Yes, every tutorial is free to read with no account required. We don't have a paid tier for core content.
Which language should I start with?
If you're not sure, we generally point beginners toward JavaScript or Python, since both have a shallow learning curve and a large number of beginner-friendly projects. The Programming Fundamentals track works with either one.
