# 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.
