数组去重的sao操作

var arr = [1,2,3,4,5,5,5,5,5,'5']
var arrr = [...new Set(arr)]
console.log(arrr)

　　转成js后

'use strict';
function _toConsumableArray(arr) { 
	if (Array.isArray(arr)) { 
		for (var i = 0, arr2 = Array(arr.length); i < arr.length; i++) {
			arr2[i] = arr[i]; 
		} 
		return arr2; 
	} else { 
		return Array.from(arr); } 
	}
var arr = [1, 2, 3, 4, 5, 5, 5, 5, 5, '5'];
var arrr = [].concat(_toConsumableArray(new Set(arr)));
console.log(arrr);

　　执行结果：

// 99758@zsh MINGW64 ~/Desktop
// $ node test.js
// [ 1, 2, 3, 4, 5, '5' ]
