使用JS从对象或映射中查找立即较少的值

function findMinValue(obj) {
  let minValue = Infinity; // 初始化为一个无穷大的值
  let minKey = null;

  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      if (obj[key] < minValue) {
        minValue = obj[key];
        minKey = key;
      }
    }
  }

  return { key: minKey, value: minValue };
}

const myObj = { a: 5, b: 2, c: 8, d: 1 };
const result = findMinValue(myObj);
console.log(`最小值为 ${result.value}，对应的键为 ${result.key}`);

function findMinValue(obj) {
  const values = Object.values(obj);
  const minValue = Math.min(...values);
  const minKey = Object.keys(obj).find(key => obj[key] === minValue);

  return { key: minKey, value: minValue };
}

const myObj = { a: 5, b: 2, c: 8, d: 1 };
const result = findMinValue(myObj);
console.log(`最小值为 ${result.value}，对应的键为 ${result.key}`);
