compare object array equals

// Compare Objects
const objectsEqual = (o1, o2) =>
    Object.keys(o1).length === Object.keys(o2).length 
        && Object.keys(o1).every(p => o1[p] === o2[p]);

const obj1 = { name: 'John', age: 33};
const obj2 = { age: 33, name: 'John' };
const obj3 = { name: 'John', age: 45 };
        
console.log(objectsEqual(obj1, obj2)); // true
console.log(objectsEqual(obj1, obj3)); // false

// Compare Object Arrays
const arraysEqual = (a1, a2) => 
   a1.length === a2.length && a1.every((o, idx) => objectsEqual(o, a2[idx]));

console.log(arraysEqual(arr1, arr2)); // true
console.log(arraysEqual(arr1, arr3)); // false
