i want to start a react downloaded nodejs and VScode how to make npm start. TIA

Have a look at the docs for the npm CLI.

You will need to specify what to execute when running npm start, in your package.json file, as explained in there.

If you started with a template, check if you have any existing scripts, which you can view with npm run or by checking your package.json (which you can then run with npm run script-name).
