计算整数数组的差值

方法一

function val(arr) {
	let max = Math.max(...arr);
	let min = Math.min(...arr);
	return max - min
}
let arr = [1, 2, 3, 4, 5, 6];
console.log(val(arr));	

方法二

function val(arr) {
	arr = arr.sort(function(x , y) {
		return x - y;
	})
	let diff = arr[0] - arr[arr.length - 1];
	return diff;
}
let arr = [1, 2, 3, 4, 5, 6];
console.log(Math.abs(val(arr)));

方法三

function val(arr){
	let max =Math.max.apply(null,arr);
	let min =Math.min.apply(null,arr);
	let diff =max-min;
	return diff;
}
let arr = [1, 2, 3, 4, 5, 6];
console.log(val(arr));

方法四

function val(arr) {
	let max = arr[0],
		min = arr[0];
	for (let i = 0; i < arr.length; i++) {
		if (max < arr[i]) {
			max = arr[i];
		}
		if (min > arr[i]) {
			min = arr[i];
		}
	}
	return max - min;
}
let arr = [1, 2, 3, 4, 5, 6];
console.log(val(arr));
