- Jeevan Bohara5 days agoThis is very easy course to learn but some of the features are only available paid user
- David P5 days agoI've gone through beginner-level JavaScript courses before, but none compare to Codecademy! The structure of this course was practically flawless. Each lesson built my understanding precept upon precept. It was laid out logically, with good reason.
- marisa m6 days agovery difficult figuring out how the descriptions lined up with the examples. some of the earlier lessons had diagrams that were very helpful.
- Julia D6 days agoVery helpful for beginners. Breaks things down into bite-sized pieces that are easily digestible. Provides a good foundation for understanding the basics of programming. The exercises are also very helpful in helping to solidify the concepts that are being taught.
- Joe F.6 days agoLearning curve quickly becomes overwhelming at Loops, and some materials are "mention first, explain later" which can be confusing. Otherwise, very good crash course!
- Tony Figueira6 days agoamazing, it looks at times too good to be true, i super recommend this Academy.
