"scripts": {
     "lint": "eslint --ext=.jsx,.js,.tsx,.ts""
},

Here, I added a file extensions for the eslint. So, it scans the following names ends with that extensions.

If you don’t have package.json file in your project directory, you can initialize it by running the npm init -y command.

npm init -y

Now, add the lint script to the package.json file.

"scripts": {
     "lint": "eslint --ext=.jsx,.js,.tsx,.ts""
},
