/Example 1: Loop Through Object Using for...in
// program to loop through an object using for...in loop

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

//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.
