Creating js and d.ts file when I built my code for checking any error

Hi everyone

I try to use built (shift+ctrl+B) for checking my code and when I do it the Visual Studio create js and d.ts files for each of my files like this:

How could I fix it?

I what’s going on in your package-lock.json file? You should have build scripts that runs that command (i prefer start to build) and the configuration could be messed up. Otherwise you should have src folder and build folder on root. Is anything changing in your build folder?
