javascript - Merge objects in array based on property -

i have array trying merge object has name property same after merge contain list of merged objects

var array = [      {name: "one",      mylist: [object1, object2]     },     {name: "two",      mylist: [object3, object4]      },      {name: "one",      mylist: [object5, object6]      } ] 

how merge 2 'one' objects

var array = [      {name: "one",      mylist: [object1, object2, object5, object6]     },     {name: "two",      mylist: [object3, object4]      } ] 

looking in vanilla javascript

firstly remove duplicate entries , organize objects inside mylist array. then, return array of objects specified keys, based on ordered object first step.

var array = [{name:"one",mylist:['object1','object2']},{name:"two",mylist:['object3','object4']},{name:"one",mylist:['object5','object6']}], obj = {};    array.foreach(function(v) {    obj[v.name] = (obj[v.name] || []).concat(v.mylist)  });    var arr = object.keys(obj).reduce(function(s,a) {    s.push({name: a, mylist: obj[a]});    return s;  }, []);    console.log(arr);
