— Carson Bartholomew

jаvascript 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 jаvascript too. And you came to the right place!

Why is this the right jаvascript course for you?



You will learn modern jаvascript from the very beginning, step-by-step. I will guide you through practical and fun code examples, important theory about how jаvascript 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 on 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 jаvascript 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 jаvascript 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.



Why am I the right jаvascript 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 700,000 developers, always listening to feedback and understanding exactly how students actually learn.

I know how students learn jаvascript 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 jаvascript 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 jаvascript patterns
  
• Master the jаvascript fundamentals: variables, if/else, operators, boolean logic, functions, arrays, objects, loops, strings, and more
  
• Learn modern jаvascript (ES6+) from the beginning: arrow functions, destructuring, spread operator, default arguments, optional chaining, and more
  
• How jаvascript 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 jаvascript: 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]
