Learn Basic Algorithmic Thinking by Building a Number Sorter - Step 44

Tell us what’s happening:

Here’s my code:

  const sortedValues = inputValues.sort((a, b) => {
    if (a < 0 && b > 0) {
      return b - a;
    } else if (a > 0 && b < 0) {
      return a - b;
    } else {
      return 0;
    }
  });

I wonder what I’m doing wrong here. I needed to return a subtraction entity, so I tried returning one.

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

  const sortedValues = inputValues.sort((a, b) => {
    if (a < 0 && b > 0) {
      return b - a;
    } else if (a > 0 && b < 0) {
      return a - b;
    } else {
      return 0;
    }
  });

“…return a single subtraction calculation using a and b that will correctly sort the numbers”

You added a lot more than a single subtraction calculation. I would reset the step to get the original code back. You don’t need an if/else statements. Only add exactly what the instructions ask and no more:

“return a single subtraction calculation”

Now I finally got it.
