i have this array and I want to compare every object parentid with another object id in same array
var array = [
{ id: 1, parentid: 2 },
{ id: 2, parentid: 2 },
{ id: 3, parentid: 2 },
{ id: 4, parentid: 5 },
];
let isparent = array.every(function (val, i, arr) {
return val.id === array[0].parentid;
});
console.log(isparent);this codes doesn't work for me !
