Enigma - Javascript Quizzes

Great app with decent interview questions and explanations, that are completely free. Only minus for me is no Angular q&a’s. But if you need to prepare for JS and React interview - this app is for you.

I was looking for an app to keep my programming skills up and test my knowledge throughout the day. I downloaded Enigma and was not impressed. For one, the application is not optimized for newer devices. It doesn’t fit the screen of my iPhone XR. In terms of the actual quizzes, they need a lot of work done. Not enough context is given, so basic questions can easily be wrong. Leaving out info like what method (const, let, var...) a variable is defined can severely impact the result of an expression, and i’ve gotten several answers wrong because of this. We need an app like this so I kindly request some work to be done. Thank-you.

The content itself in this app is good. I have enjoyed taking the quizzes, and they have helped me. However, like another user wrote, there is ver little content and the ads drive me crazy.

Way too many ads, way too little content. Great concept. But very frustrating.
