Great article! Note: I needed to assign "jest" to the "test" script in my package.json file in order for the `npm run test` script to work.

```
"scripts": {
    "test": "jest"
  },
```

Out of the box, that comes as

```
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
```

Also, I can confirm that in Oct '22, I did not need to create the .bablerc config file. I found this article because I was trying to use `spyOn` and getting the error: `SyntaxError: The requested module jest/globals does not provide an export named spyOn`. Installing the plugin to transform ES6 (modules) to CommonJS (`@babel/plugin-transform-modules-commonjs`) fixed this issue, exposing the spyOn function properly for use in my test files.
