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 / 3 days ago
