12 Things Every Junior Developer Should Learn | Code it | Scoop.it
From dev.to - October 18, 2018 11:08 PM
  • learn how a relational database works (this is always useful)
  • learn how HTTP works in general
  • learn how to debug code in one language (it's pretty much the same in others, you can recycle most of the knowledge)
  • be familiar with the command line
  • know how to find code (either using your IDE or grep on the command line)
  • knowing the basics of regular expressions will get you far (also to find code in the previous point)
  • know how to find solutions using a search engine
  • know how to operate git (I would say any source control but git is the de facto standard so you might as well start with that)
  • ask questions, especially if you think they're not worth being asked
  • learn how timezones work (not kidding, lots of devs are still fuzzy on these)
  • learn how unicode and utf-8 work (same reason for timezones)
  • have a general idea of how caching (CPU, in memory, disk, HTTP) works as a concept
