Coder Army

Master JavaScript in 22 hours the complete course from absolute beginner to advanced, taught from first principles. No memorization, no copy-paste tutorials. You’ll understand why JavaScript works the way it does, not just what to type.
This is the only JavaScript course you need in 2026. Whether you’re starting from zero or you’ve been writing JS for years without truly understanding closures, the event loop, prototypes, or async this course rebuilds your mental model from scratch.

What you’ll learn:
Variables, data types, and how JavaScript actually stores values in memory. Functions, scope, closures, and the call stack. The DOM and how the browser really renders your code. Asynchronous JavaScript callbacks, promises, async/await, and the event loop explained from the ground up. ES2026 features and modern syntax. Object-oriented JavaScript, prototypes, and the this keyword demystified. Error handling, debugging, and writing production-grade code. Real-world projects you can put on your resume.
Who this is for:

Complete beginners who want to start their developer journey the right way. Self-taught developers who can write code but feel shaky on the fundamentals. Students preparing for technical interviews. Anyone tired of tutorials that teach syntax without teaching thinking.
Why this course is different:
Most JavaScript courses teach you to copy patterns. This one teaches you to think like the people who invented the language. Every concept is built from the original problem it was designed to solve the First Thought Principle approach that has helped over 234,000 developers on this channel actually understand code instead of memorizing it.
