Tell us what’s happening:

There must be some small detail im missing here, But I just can’t see it. it’s telling me to use the addition assignment operator on calories…but i’m pretty sure I am. What’s wrong with my syntax?

Your code so far

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


/* file: styles.css */


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

function getCaloriesFromInputs(list) {
  let calories = 0;

  for (const item of list) {
    const currVal = cleanInputString(item.value);
    const invalidInputMatch = isInvalidInput(currVal);

    if (invalidInputMatch) {
      alert(`Invalid Input: ${invalidInputMatch[0]}`);
      isError = true;
      return null;
    }

    currVal = Number(currVal);
    calories += currVal;
  } 

}

Thats absolutely what it was, i literally just let it be yesterday walked away ( i had literally been coding for like 5 hours yesterday) came back with a fresh set of eyes, and it was literally that, just putting it all on one line. Thank you so much for your feedback. You guys are literally doing the lord’s work here lol.

Task:

    1. Use the addition assignment operator to add currVal to your calories total.
calories += currVal;
  • You’ll need to use the Number constructor to convert currVal to a number.

colories plus equals Number(currVal)

Hint: Task can do in one line
