Trying to understand how the parameter “data” in the line callback(data), puts the data where (json)

I am confused as to how data within the callback(data) is passing info to the “json” parameter within the arrow function that is being passed to it as a callback function.

When we pass generateHTML, the syntax matches, so it makes sense to me. But not when the arrow function is sent. Could someone explain? Thanks so much.

Ok, I think I figured it out. In order to call an anonymous function, you have to call it with (). So when the arrow function is passed as an argument, when it executes callback(), it essentially is making a call to that function. Please let me know if I’m wrong. But I tried to research it until my head started hurting lol
