  • Ashish K. (5.0/5) “This is the best JavaScript course one can look for. Great course. All the topics are explained with real life examples. The content was good and the most interesting thing about the course is that it starts from scratch zero level or from beginner to expert level with the latest Es6 modules and methods as well.”
  • Anubhav A (4.0/5) “What an amazing course this is. I have never coded in JS before but found this course to be extremely informative. Jonas has done an amazing job of explaining the syntax of the language as well as a detailed explanation of how JS works behind the scenes. The visual representation was really helpful. The course is really transparent so everyone can follow it easily. The final project was not really easy to follow due to the gap between the library versions available and by the time the course was recorded, so it may need a bit of work, although that’s a good thing as well because it shows others how complex problems can be there due to such differences. Overall, I am satisfied with this course.”
  • MANJUNATH P. (4.0/5) “Fantastic course to learn JavaScript. From very basics to advanced level, this course contains everything. Thanks Jonas and team for bringing such a valuable course. I started this course to learn the React framework, I improved a lot. I changed my way of coding, how to use modern syntax, and classes. I recommend everyone to have this course to get more grip on JS.”
  • Vikas Baburao K. (3.0/5) “It’s a little boring but it’s good for everyone. because it is designed for everyone. from scratch. so if you are new then good if you know everything but need a brush up then also good. facing issues while playing video. Audio is not coming.”
  • Yash R. (3.0/5) “It’s a very good course no Doubt, but can be explained more deeper and with examples of that particular topic. But it’s nice to take this course. I hope in future you’ll do more better.”
