Ask the library about workforce, startup, and technology trends
Answers come only from resources in this hub, with the sources listed underneath.
Free, well-written documentation and tutorials for building and hosting sites, APIs and AI workers — one of the better free places to learn modern web infrastructure.
From the site: Connect, protect, and build everywhere.
Why I recommend it: Free docs with working examples. A good self-teaching path if you want infrastructure skills on your resume.
The official free React docs, including the interactive "Learn React" course that teaches components, state and hooks from scratch with in-browser exercises.
From the site: React is the library for web and native user interfaces. Build user interfaces out of individual pieces called components written in JavaScript. React is designed to let you seamlessly combine components written by independent people, teams, and organizations.
Why I recommend it: If you want to build web interfaces, start with the official tutorial rather than a paid bootcamp — it is free and better maintained.
Google's free step-by-step tutorials for building and publishing a browser extension, from a first "hello world" to using storage, scripting and the side panel.
From the site: All the basics to get started with Chrome extensions
Why I recommend it: A small extension is one of the fastest portfolio projects you can actually finish and show someone.
XDA Developers had Claude Code (Opus 5), Codex (GPT-5.6) and Google Antigravity (Gemini 3.8) rebuild the same website from the same brief. The comparison shows which agent handles detail, polish and real-world edge cases best.
Why I recommend it: Useful if you are choosing an AI coding assistant for side projects or learning to prompt more effectively. The winner is not necessarily the one you would expect.
A Bronx-based nonprofit offering free tech training and career support in web development, data, design, and cybersecurity for underestimated talent in New York, Newark, and Atlanta.
Why I recommend it: I point career changers who cannot afford a bootcamp toward TKH. The program is community-rooted, employer-connected, and focused on economic mobility.
University of Michigan series on building database-backed web apps with HTML, CSS, PHP, SQL, and JavaScript.
Why I recommend it: Dr. Chuck teaches beginners better than almost anyone. The stack is not the trendiest, but you finish actually understanding how a web app fits together.
