It's kind of an abomination when VsCode, supposed to be a lighter IDE, runs like dogshit compared to JetBrains, a fuckin' Java based IDE. Since when was Java light on RAM?
(Caveat: I haven't directly compared their memory usage, my experience is in very difference codebases for each)
Lmao this is quite frankly, horseshit, upvoted by people who have never used an IDE.
VScode is lightweight, snappy, and fast to open. VSCodium gives you all of that without any of the Microsoft. And even runs in a web browser.
+1
For stuff like editing massive files or huge folders, the least stuttery, fastest IDE for me is... VScode. Jetbrains (last I tried it) is awful.
Code may not use 1MB of RAM or idle dead asleep, but it utilizes the CPU/GPU efficiently.
Now, extensions are the caveat, like any app that supports extensions. Those can bog it down real quick.
