Utility of node elements?

Question

Hello, I don't understand what is The utility of the document.createTextNode function?
Can someone help me please?

Answer 1

A text node is the way you can append text to an element.

You can use the appendChild function to append a textNode to an HTMLElement.

Answer 2

You can also use element.innerHTMl which stores the inner HTML and can be edited with the = sign

Answer 3

If I want a new text when the user performs an action, I have to use this function alright?
But is there another utility?
