根据JavaScript中的条件，在一系列对象中的多个字段中检查重复项

Question

我有一个对象数组，其中基于

以下条件的重复返回true或false，

如果如果类型为local local locatik code true

如果类型在或旅行中具有重复代码对象数组中的值

如果 对象数组中的值

code>在

var  objarray1=[
  {id:1, name: "ram", code: "NIXZ", type: "Local"},
  {id:2, name: "abey", code: "ABCN", type: "IN"},
  {id:3, name: "jaz", code: "ABCN", type: "IN Travel"}
]

Expected Result 
// since type-IN or IN travel and code has duplicate
false

// this code not working for above conditions
function checkArrayObject(arrobj){
   
  const getLocal = arrobj.filter(e=>e.type=="local");
  const checklocalcode = arrobj.filter(e=>e.type=="local").map(i=>i.code);

  const getIN = arrobj.filter(e=>e.type=="IN");
  const checkINcode = arrobj.filter(e=>e.type=="IN").map(i=>i.code);
  var result = arrobj.forEach(e=>{
    if(getLocal.length === checklocalcode.length) {
      return true;
    } else {
     return false;
    }
    if(getIN.length === checkINcode.length){
     return true;
    } else {
     return false;
    }
     
   }
  })
}

Answer 1

const filter = (arr) => {
  for (let i = 0; i < arr.length; i++)
    for (let j = 0; j < arr.length; j++)
      if (i !== j && arr[i].code == arr[j].code)
        return false;

  return true;
};
