What are the IDEs written in C++ and/or Python?

Question

IDE

Sublime Text is written in C++ and Python, which gives it a very high speed. The same VS Code written in Electron starts up slowly compared to Sublime Text and I would like to know if there are full-fledged IDEs written in C + + and Python?

Answer 1

Firstly, the sublime is fast not because it is a python, but because it is just a text editor, not an IDE.
Secondly, all JetBrains IDEs are conditionally slow, not because they are Java, but because they are powerful IDEs.
Do you get the logic?
PS: Well, Javascript / Electron is another story, it is basically normal if there are resources.
