What to use: computed properties or methods?

Question

JavaScript

Welcome all.
I have a textarea and a div above the textarea. The textarea expands as you type and pushes the div up. To organize this using Vue.js, I hung an EventListener in mounted , which reacts to textarea extensions and fires the resize method in methods. The resize method recalculates the height of the textarea and pushes the div up, increasing its bottom. Did I do the right thing, maybe I should use computed properties? If so, how to do it if the height of the textarea and bottom div are unknown in advance (I calculate them in mounted because I want it to look good on all screens).
Thanks in advance.

Answer 1

if the input field is already stretched, then the rest of the layout is easier to do without scripts. like flexbox.
