如何在javascript中实现多项计数器？

const counters = {
  counter1: 0,
  counter2: 0,
  counter3: 0,
};

function incrementCounter(counter) {
  counters[counter] += 1;
}

function decrementCounter(counter) {
  counters[counter] -= 1;
}

document.getElementById('incrementBtn1').addEventListener('click', function() {
  incrementCounter('counter1');
});

document.getElementById('decrementBtn1').addEventListener('click', function() {
  decrementCounter('counter1');
});

document.getElementById('counterValue1').textContent = counters.counter1;
