    I am currently learning this course and it's amazing. I went from zero to knowing how to write javascript and create apps. The best thing about Scrimba is that you can practice writing code on the page like you are writing on your own device. More importantly, I usually forget little thing from time to time and in each scrim you can save notes and review them whenever you want. I highly recommend you to try out this course and if you like it and, trust me you will, you will improve really fast in no time.

    Following this course provided me a foundational understanding of javascript from literally nothing. Being able to follow the instructor and write the code alongside theirs in the browser is so convenient and makes getting started much easier. The way the challenges are arranged so that you use what you are learning immediately is amazing for learning. I can’t recommend Scrimba enough as a learning platform and this course especially.

    This course was my first writing any JS, and it was an absolute blast. Per, the instructor, uses humor in a very efficient way, but most importantly teaches the basic concepts extremely well. The in-browser built-in code editor is really what made Scrimba for me. Being able to follow along the interactive cast makes for a great learner experience.

    I have taken a lot of courses on Javascript on other platforms, but it has never been so clearly and logicaly explained to me as this course is on Scrimba. The way the course is put together is exeptional.

    This course is pure gold, beautifully structured and allowing gradual but constant growth throughout the course. I love Scrimba and this course is one of the reasons for it!
