Use Destructuring Assignment to Pass an Object as a Function,help

Tell us what’s happening:

Forgive me for my bad English ! I finished this question. But the answer is different from mine.

get a hint answer :
return (({max, min}) => {return (max + min) / 2.0;});

why not :
return ({max, min}) => {return (max + min) / 2.0;};

Why return add a parenthesis? Is it necessary? Should I worry about it?

Your code so far*

const stats = {
  max: 56.78,
  standard_deviation: 4.34,
  median: 34.54,
  mode: 23.87,
  min: -0.75,
  average: 35.85
const half = (function() {
  "use strict"; // do not change this line

  // change code below this line
  return ({max,min}) => (max+min)/2;
  // change code above this line

console.log(stats); // should be object
console.log(half(stats)); // should be 28.015

You should not worry about it. However, if you are asked to follow that style in your work group then you just follow that.
