I'm writing some React code and noticed from my tutorial videos that their unused variables have the red squiggly lines under unused/undefined variables. For me the unused/undefined variables are greyed out, which is not helpful when there are more lines of code in a Component file.
I believe my React project is configured using Vite, and I've tried editing the "Lint" key in my package.json file, almost exhausted all VSCode/ESLint setting but still didn't get it to work. I even tried setting up external .eslintrc.json file but I don't think that's the solution either. Any idea of what I'm missing or doing it wrong?
