The ({ id }) => id part is called destructuring. It means that each item in recipes[] is an object, and we only want to look at the "id" property of that object. You can do the same thing without destructuring by writing this instead:
( item ) => item.id.

The + in front of +recipeId converts it from a string into a number, and the rest of line is just finding the object with the matching ID.
