Learn Basic Algorithmic Thinking by Building a Number Sorter - Step 7

[coloradoz99]

Tell us what’s happening:

auto coder is say map should take in dropdown param There has been no step to declare that variable.

Your code so far

const sortInputArray = (event) => {
  event.preventDefault();

  const inputValues = [...document.getElementsByClassName("values-dropdown")].map(() => {
    inputValues.value;
  });
}

There has been no step to declare that variable.

you are not declaring a variable here.
The lesson wants you to add a parameter of dropdown to your callback function.

here is another example

here is a list of numbers

const numbers = [1,2,3,4]

if I wanted to chain the map method to the numbers array and double their amount, then I can pass in a callback with a parameter of num

const numbers = [1, 2, 3, 4].map(num => num * 2);

num is the parameter name in that example. You need to do something similar for this challenge.

inputValues is an array.

your map’s callback function should have a parameter called dropdown and you should implicity return Number(dropdown.value)

hope that helps
