Solution

https://jsfiddle.net/s7s22ebp/3/

var list = document.querySelectorAll('[id^="list-block"]');

[].forEach.call(document.querySelectorAll('[id^="wow-block"]'), function(el, i){
 if (el.classList.contains('this')) {
list[i].classList.add('active');
}
});

It's cool, thanks. - Uriah commented on July 8th 19 at 11:57
