在javascript中查找两个整数l和r之间整数数组的比率

function createArray(l, r) {
  const array = [];
  for (let i = l; i <= r; i++) {
    array.push(i);
  }
  return array;
}

function countElements(array) {
  let count = 0;
  for (let i = 0; i < array.length; i++) {
    if (/* 满足条件 */) {
      count++;
    }
  }
  return count;
}

function calculateRatio(count, length) {
  return count / length;
}

function createArray(l, r) {
  const array = [];
  for (let i = l; i <= r; i++) {
    array.push(i);
  }
  return array;
}

function countElements(array) {
  let count = 0;
  for (let i = 0; i < array.length; i++) {
    if (/* 满足条件 */) {
      count++;
    }
  }
  return count;
}

function calculateRatio(count, length) {
  return count / length;
}

const l = 1;
const r = 10;
const array = createArray(l, r);
const count = countElements(array);
const ratio = calculateRatio(count, array.length);

console.log(`在范围${l}到${r}之间的整数数组中，满足条件的元素个数为${count}，比率为${ratio}`);
