数组对象去重

Posted 2020-11-22 holy-amy

 let t=[{id:1111,name:‘nnnn‘},{id:1111,name:‘nnnn‘},{id:1111,name:‘nnnn‘},{id:2222,name:‘mmmm‘}];
                let list = [];
                let idList = [];
                t.forEach((item)=>{
                    if(!idList.includes(item.id)){
                        idList.push(item.id);
                        idList = Array.from(new Set([...idList]));
                        list.push(item)
                    }
                });

思路：把数组对象去重用数组去重作为判断
