javascript 阵列中的高低数字

Posted 2021-05-03

let numsArr = [3,5,2,44,22,11,4,8,9];

const arrMin = (arr) => {
  let low = Math.min.apply(null,arr);
  console.log(low);
  return low;
};

arrMin(numsArr);

const arrMax = (arr) => {
  let hi = Math.max.apply(null, arr);
  console.log(hi);
  return hi;
};

arrMax(numsArr);


let highNum = numsArr.sort((a,b) => {
  return a -b;
});

// last num in array
highNum = highNum[highNum.length-1];

console.log(highNum);
