Error while running npm run start

Hi , Getting below error: please guide I m stuck
npm ERR! Missing script: “start”
npm ERR!
npm ERR! Did you mean one of these?
npm ERR! npm star # Mark your favorite packages
npm ERR! npm stars # View packages marked as favorites
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR! npm run

npm start is just a shortcut for npm run start, which will look in your package.json under "scripts" and if there is a "start" entry, it will execute that.

If you didn’t add a "start" script to your package.json, you will get this error message.
