how to compare objects in js code example

Example 1: how to compare javascript objects

function shallowEqual(object1, object2) {
  const keys1 = Object.keys(object1);
  const keys2 = Object.keys(object2);

  if (keys1.length !== keys2.length) {
    return false;
  }

  for (let key of keys1) {
    if (object1[key] !== object2[key]) {
      return false;

Example 2: javascript objet keys comparaison

    },
    Item2:
    {
        "bananas": "yellow",
        "pears": "green"
    }
};

var keys = Object.keys(jsObject); //get keys from object as an array

keys.forEach(function(key) { //loop through keys array
  console.log(key, key == myString)
});
