JavaScript: Understanding Advanced ES Next (ES6 and Beyond) (Udemy.com)

I took the first part about 10 years ago and it allowed me to get my first dev job. Now I took this one as a refresher as part of my preparation for job interviews. 1.75x speed worked well for me, because I was already familiar with the material, but if you're new to this - pick a slower pace. Overall the course is pretty solid, but take the first part first if you haven't yet.

I liked this course. I have 5 years of experience with JavaScript, but some of the topics were still very useful. Symbols were always unclear to me, but now I understand how I can use them. The Prototypes section was a bit confusing — for example, I didn’t fully understand the difference between __proto__ and prototype, or maybe I just missed that part. The quizzes after each section are great!

Mr. Alicea offers the best courses related to JavaScript! He may be the only instructor I have ever encountered who not only understands the language in great detail but also presents original content without imitation. I have many courses in Udemy, but this is my first comment related to a specific course.

Very easy to follow, covers the essential concepts of ES6 programming that will help optimize JS development. All topics are thoroughly explained through helpful examples. There is a quiz at the end of each chapter which I have used for continual reinforcement - they're useful to have. The course is rather short and I wish more topics were covered, a small blemish to an otherwise great learning experience.

This was my second course from Tony. His structure, use of coding examples, and calm and focused presentation make challenging topics understandable quickly and easily. Trying to build a web app for a friend's business, and I immediately bought his HTML and CSS course after finishing this one, to get a solid refresher on those topics as well.

Tony never disappoints. I am amazed how clear Tony gets with his explanations regardless of the complexity of the topics. Some topics are really advanced here, but very clear at the same time thanks to instructor's wonderful articulation of these topics. Amazing course.

Any course I EVER find taught by Tony Alicea I BUY it. He explains code, concepts so clearly you walk away UNDERSTANDING what is going on in the code and/or syntax, why it's going on and how it's going on. If you truly want to OVERSTAND this topic, or ANY topic that he teaches, you will not be disappointed. Tony Alicea just shines.

Anthony didn't disappointed me with a new addition to his original javascript course. I've been working with ES6 during a couple of years and yet Anthony's lessons gave me insights that I never saw before. His knowledge is just impressive, but is even more remarcable how delivers each lesson with such phase that you can understand them with two passes as much. He is a must when you really want to know javascript.

The course is amazing as expected from Tony. His philosophy of "Don't Imitate Understand" is excellent. It changed my perspective of looking at code. But I felt the course to be too short as compared to Tony's previous JavaScript course. I hope the author adds more content in the future. Overall a mind blowing experience.

The content delivered is of a very high level on the one hand but explained in a way that makes understanding easy and simple, I took many courses on udemy and other platforms and this combination is very rare. The lecturer's voice is also very pleasant to the ear and this detail is important when you want to complete the course. In conclusion, I am very satisfied with the course, it is worth every dollar I invested in it and even more Those who want to deeply understand what they are doing when dealing with JS code I don't know of a better substitute than this course
