Help with jQuery click event to change background color

Question

I set a div (class=“item” id=“back”)
I set css with jQuery “(document).ready”
It’s fine so far, the problem comes when I want to use addClass to this div after clicking another div (id=“joyas”)

It goes like:
$(document).ready(() => {
$(“#back”).addClass(“indexback”);
});

$(“#joyas”).click(function() {

$(“#back”).addClass(“joyasback”);

});

Notes: .indexback class has linear gradient, and I want it to change to white when clicking the div “joyas”. So the class .joyasback has a solid white background.
