  • Self taught programmers, how long did it take you to get a job that pays somewhat decently?
    So I started out with a background in design and technical writing and decided to take 3 week course in C# at the local community collage. After that I took 3 courses on Udemy where I learn HTML, CSS and React. While doing the Udemy course I also did one programming challenge at Leetcode where I uploaded the solution to my GitHub. - Source: Reddit / 4 days ago
  • Hey everybody, can anyone plz suggest some good resources to learn node.js? Would be really helpful :-)
    If you already have the fundamentals of programming down, I think the best way to learn is to head over to or 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.
