I dont understand the concept of a function in the video

function attachRemoveButton(li){ let remove = document.createElement('button'); remove.className = 'remove'; remove.textContent = 'Remove'; ***li.appendChild(remove)** }

What i do not understand is why or even how we are appending an element like a button to a list item. i would understand if I had been asked to append a new an LI element to a UL element... but to append a button elemtn to a LI element doesnt visually sit right with me. Could someone please help me digest this better

A list item can contain many different kinds of things, buttons included. You forgot to provide a link to it, but didn't the video show what the screen looks like with the button added?

all good, i forgot that the appendChild function also meant youre just giving an element another child. go figure. Thanks for your time though!
