How to get caret position in textarea?

Question

JavaScript

The task arose: when you click on the button (and there are almost 3 dozen of them), text should be inserted into the textarea where the caret is located.
But I don’t know which way to look in order to understand how to solve the problem.

Answer 1

let sel = window.getSelection();
let range = sel.getRangeAt(0);
let boundary = range.getBoundingClientRect();
