I decided to use it because it was written in Rust which seems a bit weird but I always found Rust-based softwares to be awesome. Also, it's FOSS, extension-based and most important, it's not VSCode.
Pros: its speed, stability, memory usage (~200M, which seems a lot for a texte editor, but then again I come from VSCode) fast development cycles (a whole Git interface was added recently), extensions for nearly every language, refactoring capabilities, opt-in AI agent (can be a self-hosted LLM).
Cons: not a fully-featured IDE like IntelliJ, Git client is missing features, some frameworks are not supported by extensions
I tried to use it for several projects -->
Works well: Rust, Go, VanillaJS, SolidJS (since it's using JSX/TSX, React should work too), Vue
I prefer another IDE: Angular, anything JVM related (Java, Kotlin), anything Android-related
It was DSLinux, Linux for the Nintendo DS. I tried it while hacking with the DS just to try that "Linux" everyone was talking about. I installed Ubuntu on my PC short after it.
