*** The #1 bestselling JavaScript course on Udemy! ***
*** Completely re-built from scratch in October 2020 ***
Excellent course. Jonas explains the core concepts in javascript that are usually glossed over in other courses. And he does it in a manner that is clear and concise. John Collins

Do you want to learn the number #1 programming language that powers the internet?

Are you tired of wasting your time and money on random youtube videos or JavaScript courses that are either too simple, or too difficult to follow?
Or are you struggling to deeply understand and apply JavaScript to real projects?
If your answer is a big YES... Then this is exactly the course you are looking for!
So what is the course about?
This is a truly complete JavaScript course, that goes beyond what other JavaScript courses out there teach you.
I will take you from a complete JavaScript beginner to an advanced developer. You will not just learn the JavaScript language itself, you will also learn how to program. How to solve problems. How to structure and organize code using common JavaScript patterns.
Come with me on a journey with the goal of truly understanding the JavaScript language. And I explain everything on the way with great detail!
You will learn "why" something works in JavaScript, not just "how". Because in the modern JavaScript world of today, you need more than just knowing how something works. You need to debug code, you need to understand code, you need to be able to think about code.
To achieve our goal together, the course contains coding sessions, coding challenges, theory lectures, real-world projects and a final course exam.
This course is different because it's not just about writing code, it's also about how and why code works the way it does. Because it's the perfect mix between theory and practice. Because it focuses not only on small coding examples, but also on real-world projects and use cases.
So, by the end of the course, you will be a capable JavaScript developer, able to write, understand and debug JavaScript code using all the powerful features the language offers to us.
Here is exactly what we cover in this course:
All the JavaScript and programming fundamentals: things like variables, data types, boolean logic, if/else statements, loops, functions, objects, arrays, and more.
Everything you need to know in order to gain a deep understanding of how JavaScript works behind the scenes: execution contexts, hoisting, scoping, the 'this' keyword, and more.
How to make JavaScript code interact with webpages: DOM manipulation. Learn how to select and change webpage elements, create new elements and handle DOM events.
Complex JavaScript features such as function constructors, prototypal inheritance, first-class functions, closures, the bind and apply methods, and more.
We are going to code 3 beautiful real-world apps to apply our knowledge and learn new concepts (I provide the starter HTML and CSS code for these projects).
Learn how to organize and structure your code using modules and functions, how to create data privacy and encapsulation, and why that's so important.
What's new in the most modern version of JavaScript: new features of ES6 / ES2015.
Asynchronous JavaScript: the event loop, promises, async/await, AJAX calls and APIs.

Modern JavaScript in 2018: Learn how to set up a modern development workflow with NPM, Webpack, Babel and ES6 modules.

Let's now find out if this course is for you. It's a perfect fit if...
Student #1: You want to gain a deep understanding of the most popular programming language in the world: JavaScript.
Student #2: You have taken other JavaScript courses but: 1) still don't really understand JavaScript, or 2) still don't feel confident to code real-world apps. This course is perfect for you!
Student #3: You are interested in using popular libraries/frameworks like React, Angular or Node.js.
Student #4: You want to get started with programming in general: JavaScript is a great language to learn how to code.
Now it's your turn to decide. This is what you get:
Lifetime access to HD quality videos. No monthly subscription. Learn at your own pace, whenever you want.

I completed this course early this year(have not had the chance to write my personal review on it) and I want to say a very big thanks to jonas, he goes really deep with his explanations. I totally recommended this course to lots of my friends who are interested in learning how to code. Jonas is an excellent teacher he doesn't just skim on the surface of topics but goes really further helping you to be the best you can In a short while, I have seen tremendous improvements after taking his courses and I will totally recommended it to any one. Am also patiently waiting for his node.js course??, because I know it will come with a lots and lots of value. Once again, a very big thanks to you jonas and your team!!!

Overall good course. Everything was perfectly explained. Got much-required knowledge in an easy way. Just got disappointed a bit where the lecturer couldn't explain about regular expression. A separate video about the regular expression is needed because it is also an important topic.

This is the best course online that you can get . I learn online everything about web development, but this is amazing . Thank's Jonas , you are my Hero . You give me good knowledge of Html , Css and Javascript .

By Brian Kass on 2 months ago

This is a much more advanced javascript course than i anticipated. I'm learning this language after learning python so I was plowing through most of the course the first couple weeks. however i am currently at the budget app which is challenging to say the least. I'm assuming that once I re-watch this a second time ill get everything i didnt understand but currently im pretty lost. I will not give up, and I will beat this and then ill give the five stars.

By CodeNoob Lvl1 on a month ago

This is a good course with a lot of useful information but it should definitely be listed as something strictly for advanced/experienced users. If you don't have a solid JS foundation it will be a bit too difficult which was the case for me. I highly recommend finding a JS fundamentals course first before diving into this.

By Shoham Hoffman Haik on 2 months ago

Great course ! Before the course I had small javaScript knowledge and now I feel that I know a lot more ! Thank you very much Jonas !

By nick de waal on 17 days ago

Was a great course. Good pacing, clear instructions, and interesting. I am not a beginner, but I also definitely don't know what I am doing and I found this course was a really good level for me. My only critique is that the colors chosen for the ide used in the course was sometimes quite difficult to see, so video quality could be improved upon. Otherwise a really engaging course.

Amazing Tutor, Many thanks Jonas for the course. You have explained the course so nicely. I thoroughly enjoyed the course and will be looking forward to your new courses.

Great course. It taught me a lot and now I feel like I can move on to the next step. Thanks to Jonas and his team (plus some helpful mates!). I'm looking forward to get your Node.js course Jonas!

One of the greatest courses I ever took on Udemy. It is absolutely all what I needed to know on vanilla JavaScript. It is a huge kick start for me to learn all of these in-depth concepts about JavaScript which is offered in this course and actually implement what I have been taught.
