I am lost. What would the final code be here?

Anyone know what the final code would be here and why?

script.js 
greet('cool coders');

function greet(val) {
  return `Hi, ${val}!`;
}

const greeting = ('Hi John') =>  {
  return "Hi John"

You don't have to create a new function. They want you to change the syntax of the original greet function. So keep the code in the greet function the same but change the function keyword to the syntax you have in the greeting method.

Then make should to follow the tip of declaring arrow functions before calling them.

The hint about "hoisting" lets you know that the new function needs to be first. And since you're "converting", you won't keep the old one.

But the new version needs to do the same job as the original function did, using the same argument and building the same final string using it.
