Learn Form Validation by Building a Calorie Counter - Step 42

Tell us what’s happening:

How do I go about to access the ‘length’ property of the ‘NodeList’ to get the number of entries? I would like some help from seasoned developers, please

Your code so far

function addEntry() {
  const targetInputContainer = document.querySelector(`#${entryDropdown.value} .input-container`);
  const entryNumber = targetInputContainer.querySelectorAll('input[type="text"]');
  console.log(entryNumber.length);
}

WARNING

The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

Replace these two sentences with your copied code.
Please leave the ``` line above and the ``` line below,
because they allow your code to properly format in the post.

Hi there! As said in the instructions, you have to get the number of entries using length property and you have to do this on the same line.
So you have to add .length right after querySelectorAll round brackets.
No logging any info is needed in this task

I appreciate the help. When using VS Code, what do you use to debug JavaScript files? I’m facing that issue today
