How can I do a shallow comparison of the properties of two objects with Javascript or lodash?

Question

Is there a way I can do a shallow comparison that will not go down and compare the contents of objects inside of objects in Javascript or lodash? Note that I did check lodas

Answer 1

Paul Draper's solution can be optimized by removing the compare in the second pass.

function areEqualShallow(a, b) {
  for (let key in a) {
    if (!(key in b) || a[key] !== b[key]) {
      return false;
    }
  }
  for (let key in b) {
    if (!(key in a)) {
      return false;
    }
  }
  return true;
}

Answer 2

var a = { x: 1, y: 2}
var b = { x: 1, y: 3}

function shalComp (obj1, obj2) {
 var verdict = true;
 for (var key in obj1) {
  if (obj2[key] != obj1[key]) {
   verdict = false;
  }
 }
 return verdict;
}
