Try to use it for python or c++ and you will see the problem. I switched to clion as I work in node, python and c++. vscode python support is bellow average and c++ support is bad. clion works great for all those environments.

My biggest problem with vscode is lack of UI configuration. You can have only one panel which is huge waste on big screen. Some useful features compete for screen space (outline vs. project explorer, project explorer vs. debug window etc.). This makes me way less productive than using heavyweight configurable IDE.

I use VS Code on a daily basis. It's my go-to tool for config-based projects (Kubernetes), simple and quick HTML/CSS editing, and the likes.

I've tried it for more serious development for Rust, Python, and TypeScript. While for Typescript the inference is barely acceptable it complete sucks for Rust/Python.

I use vscode daily and recommended it, but to be fair, it's heavily optimized for typescript. The feature may be not available for other language such as java.

This is true, but it demonstrates that VSCode extension model supports this, and nothing stops extension developers from attaining the same level in any other language. Hence my point about IDE/editor distinction.

Sure, why would it not be possible. Intellij and Eclipse also implement all their language support in plugins so why wouldn't VSCode.

But the thing is this is all hypothetical - it is possible if somebody invests those thousands of hours into it. But so far it did not happen for most languages and Intellij IDEs are still vastly superior to VSCode for e.g. Java, Python or C++ development.

Fair point, though I'm skeptical whether extension can achieve the same level (and performance) without vscode optimized for that.

The TypeScript support is implemented as an extension.
