1.es5做法
var array=[1,3,4,5,2,3,4,5,5,5];
var ob={};
var result=[];
array.forEach(function (a) {
???var key=(typeof a)+a;
???console.log(key)
???if(!ob[key]){
???????ob[key]=true;
???????result.push(a)
???}
???console.log(result)
})
2.es6做法
let array = [1, 1, 1, 1, 2, 3, 4, 4, 5, 3];
let newarray = Array.from(new Set([1, 1, 1, 2, 3, 2, 4]));
console.log(newarray)
js去重的es6做法和es5做法
