Welcome!

If you're new to this sort of stuff or coming back to it after mobile/backend development, here is a recommended workflow:

Install VS Code.
Install the Prettier and ESLint extensions.
Enable the VS Code setting to format on save.
Install node on your machine brew install node@20. Our package manager, yarn comes with it.

That's it. Enjoy coding!

Yarn

Note that we use Yarn classic

$ yarn --version
1.22.21

You should be seeing a 1.xx.xx version, otherwise your yarn install will fail.
