1. Set + Array.from()

var temp = [1, 1, 2, 2, 33, '33', 44, '44']
var set = new Set(temp)
console.log(set) // {1, 2, 33, '33', 44, '44'}
var setArr = Array.from(set)
console.log(setArr) // [1, 2, 33, '33', 44, '44']

1. … [拓展运算] + Set

var tt = [...new Set([1, 1, 2, 2, 33, '33', 44, '44'])]

console.log(tt) // [1, 2, 33, '33', 44, '44']
