/Example 1: Loop Through Object Using for...in
// program to loop through an object using for...in loop
const student = {
name: 'John',
age: 20,
hobbies: ['reading', 'games', 'coding'],
};
// using for...in
for (let key in student) {
let value;
// get the value
value = student[key];
console.log(key + " - " + value);
}
/Output
name - John
age - 20
hobbies - ["reading", "games", "coding"]
//If you want, you can only loop through the object's
//own property by using the hasOwnProperty() method.

/Example 2: Loop Through Object Using Object.entries and for...of
// program to loop through an object using for...in loop
const student = {

age: 20,
hobbies: ['reading', 'games', 'coding'],
};
// using Object.entries
// using for...of loop

/Output

//In the above program, the object is looped using the
//Object.entries() method and the for...of loop.
//The Object.entries() method returns an array of a given object's key/value pairs.
//The for...of loop is used to loop through an array.
