需求：对如下的数组进行去重
let stay = [{key1: 10.223,key2: 0.225},{key1: 10.01112,key2: 0.225},{key1: 10.2231,key2: 0.226},{key1: 10.223,key2: 0.22513},{key1: 10.223,key2: 0.225},{key1: 10.2231,key2: 0.226}];解决：
function handleRemove(val){
let arr = val.map(item=>JSON.stringify(item));
let result = Array.from(new Set(arr)).map((item)=>JSON.parse(item));
return result;
}
let stay = [
{
key1: 10.223,
key2: 0.225
},
{
key1: 10.01112,
key2: 0.225
},
{
key1: 10.2231,
key2: 0.226
},
{
key1: 10.223,
key2: 0.22513
},
{
key1: 10.223,
key2: 0.225
},
{
key1: 10.2231,
key2: 0.226
}];
let value = this.handleRemove(stay);
console.log(value);最后结果：
