In the below example from Codecademy, I don’t really understand how the console can process the ‘artist’ parameter in a higher-order function, considering that we’ve only declared ‘artists’ up to this point?

const artists = ['Picasso', 'Kahlo', 'Matisse', 'Utamaro'];

artists.forEach(artist => {
  console.log(artist + ' is one of my favorite artists.');
});

How can we use ‘artist’ and not something like:

artist[i]
