Long time Atom user here as well.<p>When I first tried VS Code, the first thing that I noticed was how much better the performance was compared to Atom. From general snappiness of basic editing tasks to startup times to working with large files, VS Code simply outperformed Atom across the board according to my brief unscientific observations.<p>At the time, I ended up sticking with Atom mainly because VS Code wasn&#x27;t open source and lacked extensions, but it looks like this release addresses both issues.<p>Well done, Microsoft. I&#x27;m definitely going to give VS Code another serious look and recommend other Atom users to do the same.
