Earlier this month, Vim 8.0 was released
This release is the first major release in over 10 years, and brings several new features, most exciting of which
is asynchronous I/O support. Previously, you would use a plugin like Syntastic that runs synchronously on buffer open, write or manually with a command like
:SyntasticCheck, preventing you from doing anything else while the buffer is being linted. This is far from the linting experience that modern editors like Atom/Sublime/WebStorm provide, where linters are run in the background after text is typed without disrupting your flow. In fact, this was such a badly wanted feature that it was one of the reasons why the NeoVim project came to be, among other things.
Well today, you can enjoy the future in vim.
