How to select all elements in Bootstrap pagination code using JavaScript?

I'm using Bootstrap for a website I'm preparing. Since the overflow scrollbar looked bad, I hid it with CSS and tried scrolling the pagination with the mouse wheel via JavaScript.

When I use the code given below, the top code works but the bottom code does not. When I give [0,1] as index value in JavaScript code, this time the bottom index value works but the top index value doesn't work. How can I make it work on two paginations on the same page? From what I understand from research, I may need to use let or var variables instead of const. 

const container = document.querySelectorAll(".table-responsive")[0];
container.addEventListener("wheel", function (e) {
  if (e.deltaY > 0) {
    container.scrollLeft += 100;
    e.preventDefault();
  } else {
    container.scrollLeft -= 100;
    e.preventDefault();
  }
});
.table-responsive::-webkit-scrollbar {
  width: 0 !important;
}

.content {
  width: 100%;
  height: 250px;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 3em;
}

    You can use querySelectorAll to get all elements of that class and then loop through them to add an event listener to each element. 

    const containers = document.querySelectorAll(".table-responsive");
containers.forEach(container => {
  container.addEventListener("wheel", function (e) {
    if (e.deltaY > 0) {
      container.scrollLeft = 100;
      e.preventDefault();
    } else {
      container.scrollLeft -= 100;
      e.preventDefault();
    }
  });
});
