Not quite so. You need to explicitly run a linter, then look up the code lines that it's complaining about. In an IDE, you will have the lines marked while you are writing the code. Plus you get code completion and so on. Working in a pure text editor works if you have a relatively small piece of code you can focus on while working, but I've seen very experienced engineers become extremely slow or completely fail with their vim setup when they suddenly work on something that's beyond the 20k line mark.
