Angular & JavaScript Interview: Top 400 Questions (2026) (Udemy.com)

Great course. The instructor is very organized and provides a PDF of the lectures, which is excellent for quick review. The lectures are clear, concise, and not overloaded with redundant chatter. That is especially valuable for people taking online training while balancing other responsibilities and tight schedules. He respects students’ time by giving just the right amount of information and examples to build solid understanding and prepare for junior to mid-level interview questions.

Excellent course! The trainer explained each topic in depth, making it easy to understand and apply.

Exceeded expectations! Thank you for providing very detailed and clear answers for all the questions!

Very clear explanation. And highlighting in which version what is introduced this concepts will put values to understand on depth.

Excellent Course – Highly Recommended! I really enjoyed this course. The instructor explained concepts clearly and provided practical examples that made the lessons easy to follow. The structure was well-organized, starting from the basics and gradually moving to advanced topics, which helped me build confidence step by step. The pace was perfect, and the instructor was engaging throughout. Overall, this course exceeded my expectations and gave me valuable skills I can apply immediately. Highly recommended for anyone interested in this subject!

The course is good, but it doesn't include all the questions. Some questions as well as some explanations are missing. I asked a question 3 days ago, but the instructor hasn't replied me yet. So, I am still waiting for my answers.

This is the second Top X Questions I've bought that Happy has done, both this one and the .NET one were fantastic. Happy does a great job of breaking concepts into their base pieces so that he can explain them clearly and concisely.

This is an excellent course compared to other React courses. It gets straight to the point without wasting any time. I discovered this course through YouTube and decided to purchase the JavaScript course first, which was also great. If you have previous programming experience in any language, you'll find it easier to follow. I completed the JavaScript course in just 2 days due to my background in Java. Subsequently, I finished the React course in just 3 days. With my prior knowledge of Java and Spring Boot, I now have proficiency in HTML, CSS, Bootstrap, JavaScript, and React. In just 5 days, I transitioned to a full-stack developer. I have one request for the instructor: if possible, please create similar courses for Java, Spring Boot, microservices, SQL, and NoSQL.

Awesome Course!! Crystal clear explanation of each and every questions. Would like to recommend to each and every one of you whoever is looking to crack full stack developer/front end developer interviews. Thanks a lot Sir!! Keep up the good work!!

Very clear and detailed. Guaranteed one day preparations of the interview by keeping all aspects of interviewer in mind. Appreciated it!
