commonKeys(obj1, obj2) This method will return a new object with key-value pairs that exist in both objects. Objects as values are valid. If no common keys are found, return an empty object. For example, if given the following: {a: 2, b: 4}; {a: 5, b: 4}; const first const second = = {a: 2, b: {x: 7}}; const fourth = {a: 3, b: {x: 7, y: 10}}; const third console.log(commonKeys(first, second)); // {b: 4} console.log(commonKeys(first, third)); // {a: 2} console.log(commonKeys(second, third)); // {} console.log(commonKeys(third, fourth)); // {b: { x: 7}} console.log(commonKeys({}, {})); // {} • You must check that each argument is provided • You must check that each argument is an object. If any of those conditions fail, the function will throw. Empty objects are valid as shown in the last example above. Remember: The order of the keys is not important so: {a: 2, b: 4} is equal to {b: 4, a: 2}
