const student = {

};

// using for...in
for (let key in student) { 
    let value;

    // get the value
    value = student[key];

    console.log(key + " - " +  value); 
}

	name - John
	age - 20
	hobbies - ["reading", "games", "coding"]

//own property by using the hasOwnProperty() method.

if (student.hasOwnProperty(key)) {
    ++count:
}

//The for...of loop is used to loop through an array.
