Pure Javascript listen to input value change

Is there any way I can create a constant function that listens to an input, so when that input value changes, something is triggered immediately?

Another approach in 2020 could be using document.querySelector():

const myInput = document.querySelector('input[name="exampleInput"]');

myInput.addEventListener("change", (e) => {
  // here we do something
});
