We break down:

* ✅ What to learn (and **why** each concept matters)

* ✅ How to structure your learning path without getting overwhelmed

* ✅ The **hard truths** about JavaScript in the real world

* ✅ Mistakes that beginners make (and how to avoid them)

* ✅ How to go from *tutorial nightmares* to building projects that actually get you hired

“You don’t need 50 tutorials, you need 20 projects that work your brain in the right way.”

We cover everything from fundamentals (variables, loops, functions) to advanced topics like async/await, the event loop, testing, and working with frameworks like React and backend tools like Node.js. We don’t just tell you *what* to learn — we tell you *how to think like a developer*.

Whether you're headed toward a front-end career, full stack mastery, or just want to build real apps, this roadmap will serve you today and 10 years from now. No fluff. No hype. Just honest, actionable advice from two developers who have taught thousands of devs to land six-figure jobs.

Leave a comment with the word (gotta watch to the end) if you made it to the end. We want to shout out the real ones.
