// There are several ways to convert an object to an array in JavaScript.

// One way is to use the Object.keys() method to get an array of the object's keys, and then use the map() method to iterate over the keys and create a new array of key-value pairs.

// Here's an example:

const object = {
  a: 1,
  b: 2,
  c: 3
};

const array = Object.keys(object).map(key => [key, object[key]]);

console.log(array); // [['a', 1], ['b', 2], ['c', 3]]

// Another way is to use the Object.entries() method, which returns an array of the object's key-value pairs:

const array = Object.entries(object);

console.log(array); // [['a', 1], ['b', 2], ['c', 3]]

//You can also use a combination of the for...in loop and the push() method to iterate over the object's keys and create an array of key-value pairs:

const array = [];

for (const key in object) {
  array.push([key, object[key]]);
}

console.log(array); // [['a', 1], ['b', 2], ['c', 3]]


Thank you :)
