I have question on why this is wrong. I used query selector to select all the elements which is different from the solution in the video. The video used the getElementsByTagName and looped it.
// 6: Change all <input> elements from text fields to checkboxes const allInputElements = document.querySelectorAll('input'); allInputElements.type = 'checkbox';

But either way, you can't assign the "type" attribute of all the elements of a collection with a single operation. You'd need to loop through the collection and assign them individually.

15,843 Pointsmy solution to looping over the input's with the querySelectorAll is this:
let allInputElements = document.querySelectorAll('input');
for (let i = 0; i<allInputElements.length; i++) {
allInputElements[i].type = 'checkbox';
}
This is the same as in the video, the only difference is that you made a list with the input elements with the query selector instead of getElementsByTagName.
Hope this helps.

9,673 PointsThanks for the reply. I see. So then if I can loop through the elements using the querySelectorAll somehow then would it be a sufficient way to change the type attributes?

231,269 PointsBoth "querySelectorAll"and "getElementsByTagName" give you an iterable collection that you can use in a loop.

9,673 PointsI see. I will trying searching for a way to use querySelectorAll to iterate over the elements. Thanks for the answers.

231,269 PointsBesides using it in a loop, you can also apply the "forEach" method to it.
