Try checkio.org or codewars.com I used checkio.org while I was reading Mark's book. - Source: Reddit / about 3 hours ago
If you already have the fundamentals of programming down, I think the best way to learn is to head over to leetcode.com or codewars.com and do a bunch of programming challenges in that language. This gets you familiar with the basics really quickly as well as all the node documentation. I learned Python in about a week using codewars.com (I already had 3.5 years in school as a cs major though). - Source: Reddit / 4 days ago
I used codewars.com with Golang reference website and solved tasks (katas) on Golang. - Source: Reddit / 6 days ago
There are some innovative resources that I found useful for learning python - but I was already an experienced programmer... checkio.org, codewars.com looks similar. These sites offer coding problems and then let you see the results of others. This was a significant learning accelerator for me. - Source: Reddit / 8 days ago

One great website for coding puzzles is Project Euler! It helped me so much when I first started programming, and when I got into making stuff for games I felt my ability to create unique solutions to problems was greatly improved. - Source: Reddit / 1 day ago
In a similar vein project Euler is a good one for practice problems if you have more of a mathematical leaning. - Source: Reddit / 2 days ago
"Math" and "mini projects" makes me think Project Euler. - Source: Reddit / 4 days ago
This visualisation was inspired by the 27th problem of Project Euler. I won't go into detail about the problem itself (if you're interested you can check it out at https://projecteuler.net/), but the idea was to look at how many consecutive primes would be generated by polynomials of the type n²+an+b. "Consecutive" means that you'd start with n=0, calculate the polynomial and see if it generates a prime number.... - Source: Reddit / 5 days ago
