javascript find intersection beween two sets [duplicate]

Im trying to check intersection between two sets and insert into an array or a new set, but without success here is what I wrote

let intersection=[] ;       let a40=[1,2,3,5];       let a50=[1,20,30,5];       let unique1 = [new Set(a40)];      //console.log(unique1);      let unique2 = [new Set(a50)];     // console.log(unique2);   for (var i = 0; i < unique1.length; i++) {   if (unique1[i] in unique2 )   {   intersection.push(unique1[i]);   }   else{   //no   }   console.log(unique2);   }
