VS Code is not only the best free open source editor on the market, but also has the best Linux support I have found.
Microsoft’s current strategy is to love all things Linux, and they are throwing their full support behind this amazing editor. It even has it’s own dedicated RHEL, Fedora and CentOS repository.
The pace of development on VS Code is amazing, they bring out a new version every month without fail. Just when you think it can’t get any better, they add another feature that you soon won’t be able to live without. It is much more responsive than Atom, even though it uses the same Electron framework. It has build in GIT version control tools, debugging, intelligent code completion, a task runner, and whatever is not built in, someone has made an extension for it.
