我刚开始使用JavaScript，但我认为这个方法会很好:

var array = [34, 23, 57, 983, 198];
var score = 0;

for(var i = 0; i = array.length; i++) {
  if(array[ i ] > score) {
    score = array[i];
  }
}

最简单的语法，使用新的展开操作符:

var arr = [1, 2, 3];
var max = Math.max(...arr);

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(…);

Use:

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

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

console.log(largest);

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);

试试这个

function largestNum(arr) {
  var currentLongest = arr[0]

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

  return currentLongest
}
