As we can't access data from Object directly or perform operations on that.Firstly we have to convert the object in an array format then only we can apply functions .

In JavaScript, you can access the properties and values of an object in several ways. Here are the most common methods:

1 . Dot Notation ()

_the popular one _
Ex:
const person = {
name: "John",
};

console.log(person.name); // Output: John

2 . Bracket Notation
(Suitable for when object contain spacing in key )

const person ={
first name='Panchi';
}
console.log(person['first name']);

1. Accessing All Keys and Values [ IMP] You can use Object.keys(), Object.values(), or Object.entries() to get all keys, values, or both

const person = {
name: "John",
age: 30,
city: "New York"
};

console.log(Object.keys(person)); // Output: ["name", "age", "city"]
console.log(Object.values(person)); // Output: ["John", 30, "New York"]
console.log(Object.entries(person));// Output: [["name", "John"], ["age", 30], ["city", "New York"]]

** NOTE : Object.entries used to return array then on that resulting array we can apply like .map() or .filter function.**

Moreover Resulting array contain data like enum in key value pair
