//* Programming Challenge: Convert Object to Array and Vice Versa
//*-
//* Your task is to implement two functions:|

//? Convert Object to Array: Write a function objectToArray that takes an object as input and returns an array of key-value pairs, where each element in the array is an array with two elements: the key and the corresponding value from the object.
//? Convert Array to Object: Write a function arrayToObject that takes an array of key-value pairs (as returned by the objectToArray function) and returns a new object with the keys and values from the array.
//? Ensure that the conversion functions work correctly for objects with various data types as values, such as strings, numbers, and objects.
//* Constraints:
//? The input object may contain properties of any data type.
//? The input array must contain arrays with exactly two elements


const obj = {
    name: "satyam singh",
    age: 22,
    city: "mumbai",
};

// convert the object into the array of key-value pairs
let entries = Object.entries(obj);

console.log(entries);
// output [ [ 'name', 'satyam singh' ], [ 'age', 22 ], [ 'city', 'mumbai' ] ]
console.log(entries.flat());
// output [ 'name', 'satyam singh', 'age', 22, 'city', 'mumbai' ]


// Convert the array of key-value pairs back to an object.

let newobj = Object.fromEntries(entries);
console.log(newobj);
// output { name: 'satyam singh', age: 22, city: 'mumbai' }
