const missingDeepKeys = require('missing-deep-keys');
const o1 = {a: {b: 2}}; // Base object
const o2 = {c: 1}; // Comparison object
const result = missingDeepKeys(o1, o2);
// Prints keys present in o1 but missing in o2
console.log(result); // => ['a.b']
// Additionally include a parent object if its children are missing
const result2 = missingDeepKeys(o1, o2, true);
console.log(result2); // => ['a', 'a.b']Returns an array of keys present in o1 but missing in o2
