i have an Array of Objects each Objects have an (Id,num) properties

const arrayofDuplicates = [
    {num:1,id:25},
    {num:1,id:25},
    {num:2,id:2}, 
    {num:3,id:3}, 
    {num:1,id:25},
];

now what i want to do is to Remove the Duplicate Objects from my Array so i created a function that loops over the Array and filter the duplicates and return a new Array without the Duplicates the Problem i have here is that it Returns the Same Array with the Duplicates like if nothing changed

const FindDuplicate =(duplicareArr,layerId)=>{
  const duplicateVal=duplicareArr.find((el)=>el.id===layerId)
  console.log(duplicateVal)
  return  duplicateVal 
}
const values = arrayofDuplicates.map((el,index,arr)=>{

    const FilteredObject= FindDuplicate(arr,el.id)
    return FilteredObject;
}
