Anyone can tell me what is this ___ in function? And how this code is working? Thank you in advance

If your code is correct it will run…or error will show

You don’t need to add anything into those ___ spots in the code. Try running the code. From what you have shown in your screenshot, it should accept your answer to the puzzle.

The instructions only have one step:

• Change max = num to max = larger(max, num)

This is the official solution for this puzzle (click arrow to reveal further details):

sample solution code

function larger(a, b) {
  return a > b ? a : b;
}

function maximum(array) {
  let max = 0;
  for (let num of array) {
    max = larger(max, num);
  }
  return max;
}
console.log(list);
console.log(maximum(list));

Hey there, let’s take a look at how the functions work. function larger(a, b) { return a > b ? a : b; } The larger function takes 2 numbers and returns whichever one is largest. It calls these numbers a and b in the function declaration. If a > b, then the function returns a. Otherwise it returns b. The maximum function takes an entire array of numbers, and returns the largest number in the array. function maximum(array) { let max = 0; for (let num of array) { max = larger(max, nu…

When a variable is declared with let, it can be accessed inside the code block where it is declared, and any child code blocks. That’s why the line inside the for loop can access and update the value of max: function maximum(array) { let max = 0 // max is scoped to the entire function for (let num of array) { max = larger(max, num); // max is in scope because // this code block is inside the function // therefore we can change the value of max } return max; } Varia…
