"This course covers far more ground than any other JS course I've done. If you take this course you can start knowing nothing and finish with some really advanced knowledge, a professional standard application that can be used as a portfolio piece to present when applying for jobs and an appetite for more study.
I will buy any future courses from this tutor" Rob Masters

"This is one of the best javascript courses I have taken. The examples and explanations are clear and to the point.
What I really like about this course is that for each video, you can download the starter code as well as the completed code. Open the starter code in the code editor and you can follow along with the instructor as he completes the topic. If you have a problem, you can always open the completed code file that is included to see where you went wrong.
I look forward to more courses from Development Island." Steven Wellman

"Fantastic Course..!
Issam's teaching method is very clear and concise. He builds concepts from the ground up to the advanced very smoothly and steadily.
The Typing Speed App is huge and consists of many advanced techniques to explore.
I've already taken Issam's "Complete Web Development Course - Build 15 projects". Both his courses are amazing and suited for all levels. There's always something to learn even if you are an advanced students.
Taking both of his courses are the best thing ever happened to me in my Web development learning experience.

One of the most descriptive Javascript course I've seen. This is Great, I used javascript and angular in past but I never knew how Javascript works internally, and thanks to this course It sheds some light. A lot of other Javascript courses only show what the syntax do, but this course also explains how the syntax works and why it does what it does :D . This Javascript course is for absolute beginners, for people who do not understand how Javascript works, and for people who has the dedication and patience (a lot of it) to learn Javascript. If you're not one of the above mentioned this is not for you. I only gave 4 stars because this course lacks the built-in HTTP functions and localStorage but still a great course.

The best course on JS that I have ever seen here in Udemy. I am really happy with the course. What I like the most is how detailed he is and he really takes his time to teach you everything. I just learned many things I didn't know. Thank you.

A lot of effort has been put into creating this course. A lot of content also.

The other Development Island course I took I enjoyed tremendously.The Complete Modern Javascript Course with ES6(2019) has all the ingredients for a beginner.The tasks / challenges are set at the right level for a beginner and move on to more challenging tasks which will cater for more competent javaScript coders.There are good examples and many short do-able challenges.The challenges / tasks do start off at a appropriate level but increase in complexity. The type writer app is a good example. It is complex but well worth completing.Take your time watching the videos and practice as much as you can with your own code as well.

At this point, it is a little too slow. However, I am reserving final opinion until after the last ES6, OOP, ...

I'm only about a quarter of the way through this course but more than happy to give it 5 stars. Baffling why this guy doesn't have more students - tons of material here, with good explanations and - crucially for me when it comes to coding courses - a nice sprinkling of challenge exercises to help you gauge whether you're really 'getting it' or not. If you want to learn Javascript we all know you have a ton of options but this course deserves to be on your shortlist in my opinion.

This course covers far more ground than any other JS course I've done. If you take this course you can start knowing nothing and finish with some really advanced knowledge, a professional standard application that can be used as a portfolio piece to present when applying for jobs and an appetite for more study.I will buy any future courses from this tutor

Very clear and detailed approach. Included some important information which I did not find elsewhere, which was great. The diagrams are always very helpful as well. Very nice course.

Very comprehensive course that takes you thru every step of the JavaScript language, then leads you to and thru a practical professional project

Just Amazing Course with good and clear things. It's help me to learn more new things with Particles Step By Step.Thanks !!

Overall, I'm now more opened and prepared to continue with more JavaScript higher order functions just by paying attention to this lovely course. Great Job Sir...!!!

Estou gostando muito do curso.O contedo excelente! J estudei em outros cursos online como codecademy PRO e freeCodeCamp e arrisco a dizer que o contedo desde curso est mais completo e muito mais didtico para iniciantes do que outros.Para estudantes estrangeiros como eu, o instrutor tem um sotaque bastante fcil de entender e isto facilita muito acompanhar as aulas(tenho nvel de listening intermedirio e n�o tive dificuldades)Enfim, recomendo 100%
