Use:

var arr = [1, 2, 3, 4];

var largest = arr.reduce(function(x,y) {
    return (x > y) ? x : y;
});

console.log(largest);

你可以对数组进行降序排序，得到第一项:

[267, 306, 108].sort(function(a,b){return b-a;})[0]

应该很简单:

var countArray = [1,2,3,4,5,1,3,51,35,1,357,2,34,1,3,5,6];

var highestCount = 0;
for(var i=0; i<=countArray.length; i++){    
    if(countArray[i]>=highestCount){
    highestCount = countArray[i]
  }
}

console.log("Highest Count is " + highestCount);

一个for/of循环解决方案:

Const数= [2,4,6,8,80,56,10]; const findMax =(…numbers) => { let currentMax = numbers[0];/ / 2 For (const number of numbers) { if (number > currentMax) { console.log(数字,currentMax); currentMax = number; ｝ ｝ console.log('最大'，currentMax); 返回currentMax; }; findMax数量(…);

在数组中返回最大数字的解。

const largestOfFour = arr => {
    let arr2 = [];
    arr.map(e => {
        let numStart = -Infinity;
        e.forEach(num => {
            if (num > numStart) {
                numStart = num;

            }
        })
        arr2.push(numStart);
    })
    return arr2;
}

使用冒泡排序找到最大和最小值

Var arr = [267, 306, 108]; (i = 0 k = 0;我< arr.length;我+ +){ (j = 0;<我;j + +) { 如果(arr[我]> arr [j]) { K = arr[i]; Arr [i] = Arr [j]; r[j] = k; ｝ ｝ ｝ console.log('最大数字:'+ arr[0]); console.log('最小值:'+ arr[arr.length-1]);
