输入：
let arr = [{
name: '111',
value: 'hello'
}, {
name: '222',
value: 'world'
}, {
name: '111',
value: 'hello'
}];
console.log(removeDuplicateObject(arr));
输出：
[{name: '111',value: 'hello'}, {name: '222',value: 'world'}];
一组对象去重removeDuplicateObject方法的一种实现
function removeDuplicateObject (arr) {
let temp = arr.map((item) => {
return JSON.stringify(item);
});
temp = Array.from(new Set(temp));
return temp.map((item) => {
return JSON.parse(item);
});
}
