Course Overview
The modern JavaScript course for everyone! Master JavaScript with projects, challenges and theory. Many courses in one!
The #1 bestselling JavaScript course on Udemy!
Just updated with ES2024 and ES2025!
"Really, really well made course. Super in-depth, with great challenges and projects that will solidify your Javascript understanding. I found the lectures were paced perfectly -- Jonas doesn't skip over anything that might be useful to a JS developer" — Carson Bartholomew
JavaScript is the most popular programming language in the world. It powers the entire modern web. It provides millions of high-paying jobs all over the world.
That's why you want to learn JavaScript too. And you came to the right place!
Why is this the right JavaScript course for you?
This is the most complete and in-depth JavaScript course on Udemy (and maybe the entire internet!). It's an all-in-one package that will take you from the very fundamentals of JavaScript, all the way to building modern and complex applications.
You will learn modern JavaScript from the very beginning, step-by-step. I will guide you through practical and fun code examples, important theory about how JavaScript works behind the scenes, and beautiful and complete projects.
You will become ready to continue learning advanced front-end frameworks like React, Vue, Angular, or Svelte.
You will also learn how to think like a developer, how to plan application features, how to architect your code, how to debug code, and a lot of other real-world skills that you will need in your developer job.
And unlike other courses, this one actually contains beginner, intermediate, advanced, and even expert topics, so you don't have to buy any other course in order to master JavaScript from the ground up!
But... You don't have to go into all these topics. This is a huge course, because, after all, it's "The Complete JavaScript Course". In fact, it's like many courses in one! But you can become an excellent developer by watching only parts of the course. That's why I built this course in a very modular way, and designed pathways that will take you through the course faster.
By the end of the course, you will have the knowledge and confidence that you need in order to ace your job interviews and become a professional developer.
Why am I the right JavaScript teacher for you?
My name is Jonas, I'm an experienced web developer and designer, and one of Udemy's top instructors. I have been teaching this bestselling course since 2016 to over 850,000 developers, always listening to feedback and understanding exactly how students actually learn.
I know how students learn JavaScript and what they need in order to master it. And with that knowledge, I designed the ideal course curriculum. It's a unique blend of real-world projects, deep explanations, theory lectures, and challenges, that will take you from zero to an expert and confident JavaScript developer in just a couple of weeks.
So what exactly is covered in the course?
Build 5 beautiful real-world projects for your portfolio! In these projects, you will learn how to plan and architect your applications using flowcharts and common JavaScript patterns
Master the JavaScript fundamentals: variables, if/else, operators, boolean logic, functions, arrays, objects, loops, strings, and more
Learn modern JavaScript (ES6+) from the beginning: arrow functions, destructuring, spread operator, default arguments, optional chaining, and more
How JavaScript works behind the scenes: engines, the call stack, hoisting, scoping, the 'this' keyword, reference values, and more.
Deep dive into functions: arrow functions, first-class and higher-order functions, bind, and closures.
Deep dive into object-oriented programming: prototypal inheritance, constructor functions (ES5), classes (ES6), encapsulation, abstraction, inheritance, and polymorphism. [This is like a small standalone course]
Deep dive into asynchronous JavaScript: the event loop, promises, async/await, and error handling. You will use these to access data from third-party APIs with AJAX calls. [This is like a small standalone course]
Learn modern tools that are used by professional web developers: NPM, Parcel, Babel, and ES6 modules

Very good job Jonas, the course is up to date so no issues following in sections where you need to use external ressources like APIs. The Forkify app at the end is a true asset where we can see how to organize the code and design the architecture on a bigger project.

This course is great for understanding the basics of JavaScript syntax, concepts, and implementation through small projects. Some of the projects may be a bit outdated, but the concepts and syntax are still usable for beginners, and any minor issues can be fixed with your ChatGPT tutor 😏. It's a good practice for building a foundation. What I really like is that it teaches you how to design a website step by step, focuses on JavaScript with different working flows, demonstrates the MVC architecture, and deploys it in the final project. Thanks🤞
