Assigning same eventlistener to multiple btns?

1

Hey!
If you had a set of buttons called: bt1, bt2, bt3 etc all the way to “bt11” and you wanted to assign the same eventlistener to all of them how would you go about this? ie:

bt1.addEventListener(MouseEvent.CLICK, closeShutters);
bt2.addEventListener(MouseEvent.CLICK, closeShutters);
bt2.addEventListener(MouseEvent.CLICK, closeShutters);
etc (too repetitive)

Thanks for any help!
