If you have problems with your VS Code that uses over 100% of CPU on Windows or 30–40% on Linux, I may have a solution for you. The problem causing this is often TSServer. And with small edit in settings, you can get to 1–5% CPU on Large projects as I have. Just go to settings.json and add these lines: "files.useExperimentalFileWatcher": false,
"typescript.validate.enable": false,
"javascript.validate.enable": false,
"files.watcherExclude": {
"**": true
}
