JS-函数求最值

求数组中的最大值

	function getMax(a) {
            let max = a[0]
            for (let i = 0; i <a.length ; i ++) {
              if(a[i] > max) {
                  max = a[i]
              }
              }
              return max
        }

        let num = getMax([1,8,6,3,3,7])
        document.write(num)

求数组最小值

function getMin(a) {
            let min = a[0]
            for (i = 0; i < a.length ;i ++) {
                if(a[i] < min) {
                    min = a[i]
                }

            }
            return min
        }
        
        let num = getMin([1,4,2,5,7,2,0])
        document.write(num)

求任意两个数中的最大值

   function getMax (num1,num2) {
        let max = num1
        if(max < num2) {
            max = num2
        }
        return max
    }
    let max = getMax(3,7)
    document.write(max)
