Tell us what’s happening:
Want to ask how does the computer gets to know that the arguments {min, max} in function half are from stats?

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 function half({min,max}) {
    // use function argument destructuring
    return (max + min) / 2.0;
  };
  // change code above this line

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

Look at the log lines below the code. The user passes an object to the function half. The javascript interpreter then compares the object to the oarams and sees that the params are properties of the object so it grabs the values and passes them in.
