After this lesson, you will be able to: Know the professional tools and learning paths that take you from "I can build a website" to "I can build production software."
You finished the track. This lesson is a guided tour of the next steps, the tools, frameworks, and concepts professional developers use day to day, plus where to find good learning resources for each of them.
VS Code as the editor (or its AI-native sibling, Cursor). Git and GitHub for version control and collaboration. Chrome DevTools for inspecting and debugging. Postman or Insomnia for testing APIs. ChatGPT or Claude for explanations and rubber-ducking.
Git tracks changes; GitHub hosts your code. Together they're how every team works on software.
Install Git (git-scm.com) on your computer or use it in the terminal in your editor
Learn the daily commands: git status, git add, git commit -m, git push
Create a free GitHub account and connect it to your local Git
Make a repository for your full-stack project from last lesson
Learn branching: git checkout -b feature/new-thing and pull requests
Plain HTML/CSS/JS is the foundation, but real apps use frameworks. React (and Next.js) is the dominant frontend framework, it lets you build UIs as reusable components. Tailwind CSS is the dominant styling system, utility classes that make styling fast and consistent. TypeScript is JavaScript with types, it catches errors before you run the code and is now standard at most companies.
BiTree teaches every concept in this track end to end, but if you want more reps or a second voice explaining the same idea, these external sites are well-respected. Treat them as supplements, not replacements: come back here for the structured path. MDN Web Docs is the deep reference for everything HTML, CSS, and JavaScript. W3Schools and Khan Academy have shorter explainers and quick interactive snippets. freeCodeCamp has long-form free curricula. CS50 (free from Harvard) is the gold standard for computer science fundamentals. The Odin Project bundles a self-paced full-stack JS curriculum. MIT Terminus is a browser-based terminal puzzle game that drills shell commands (we'll ship our own version of this inside BiTree soon).
