It's useful as a reference tool for web… It's useful as a reference tool for web programming. But it focuses too much on the syntax of all the different programming languages (which is similar in them all) and doesn't explain adequately why you would use a particular technology over another, and how to incorporate it into your website.

Best It's simply the best, you can find everything, you can learn everything, and especially, the test helped me during my exam to be sure I knew everything ! Keep up, and try to diversify also to other language please :)

Pandas course - don't pay for it! This is about the Pandas course. It said it would be about 4 hours and I would get a certificate at the end. I know a thing or 2 about database languages and the pandas course was a very big disappointment. Don't pay for it, just do it for free online. It took me about an hour, the "exam" was regurgitation via multiple choice. Nothing about merging or filtering data or doing any useful analysis. Very basic. I really regret paying.

They did great with the tutorials They did great with the tutorials! The thing that I would change would maybe making the amount of data in the spaces to be a little bigger, but overall, fantastic!
