Functions for working with a group of DOM elements

Let's now write a function that takes a group of elements selector and their new text as parameters. Let this function set new text to all elements, matching for the selector.

Let's implement the described function:

function setText(selector, text) { let elems = document.querySelectorAll(selector); for (let elem of elems) { elem.textContent = text; } }

Let's test it for a group of the following elements:

<p class="elem"></p> <p class="elem"></p> <p class="elem"></p>

Set new text for all elements with class elem:

setText('.elem', 'text');

Make the appendText function that takes a selector as the first parameter and text as the second. Make this function append text to the end of passed elements.
