I held out for a year or so after VSCode was released. It felt scummy how MS had swooped in and tried to hijack this new category of editor that GitHub had invented (this was before they'd been acquired, I believe)<p>But once I tried VSCode... man, there was no going back. It was infinitely more performant and cohesive. Atom (with IDE-like features installed) felt so sluggish by comparison. I think the main improvement was how opinionated VSCode and its extension APIs were; Atom extensions could have <i>dependencies on each other</i>. I remember you had to install an extension for generic IDE hover-overs and such, before installing the actual language plugin, and then there were <i>competing standards</i> for which generic hover-over framework each language wanted to use. It didn't just complicate the user-experience, I'm convinced this was the reason the editor would get so slow; the APIs were too low-level and all the plugins were fighting with each other instead of going through standard channels.<p>But, Atom will always have a special place in my heart. It blazed new trails in editor customizability (even if the degree ended up being its downfall, quite a bit of that legacy can still be found in VSCode). It invented the entire concept of web apps as desktop apps, which despite what some here would tell you, I think is a very good and important thing. And it always had such a fun, community feel to it that's been mostly lost with VSCode.<p>It was time, but I will miss it. I'll close off with the very cute and fun Atom 1.0 announcement video: <a href="https://youtu.be/Y7aEiVwBAdk" rel="nofollow">https://youtu.be/Y7aEiVwBAdk</a>
