There is an exercise about async Callbacks an I am trying to solve it but I get error. How can I solve it?

Write a function called printAsyncName, which will take as parameters a callback and a string (which will be name). The callback function will simply print "Hello". The printAsyncName function will have to execute the callback function after an interval of 1 second. After an interval of 2 seconds, we must print the name that we take as a parameter.

Tips:

• The setTimeout method will be useful
• The callback function must be an arrow function, can you also explain why?

function printAsyncName(sayHello, name) {
  setTimeout(() => {
    console.log(name);
  }, 2000);
  let hello = setTimeout(() => {
    console.log("Hello");
  }, 1000);
  sayHello(hello);
}

printAsyncName("Jack");

And this is the error I got:

Process exited with code 1
Uncaught TypeError TypeError: sayHello is not a function

  setTimeout(() => {

  }, 2000);
    setTimeout(() => {
        callbackFunction;
  }, 1000);
}

callback = () => console.log('hello');
printAsyncName('John', callback())
