I Wish their data set wasn't so biased. 72% of respondents found freecodecamp helpful? Well that answers almost everything about who they're talking to!

Doesn't seem like a fair representation of people who are learning to code. There are 40,000 computer science graduates per year. So perhaps 160k to 200k CS majors at any given moment. Those people learning program doesn't seem to be represented at all in this survey.
