javascript iterate object

const person = {
	firstName: 'John',
	lastName: 'Doe',
  	email: '[email protected]'
};
for (const [key, value] of Object.entries(person)) {
	console.log(`${key}: ${value}`);
}

/*
	Explanation - 
    Object.entries(person) returns: [["firstName","John"],["lastName","Doe"],["email","[email protected]"]]
    We can use an ES6 'for-of' loop to interate over it. Each iteration gets an 
    array where the 0th index is the property name and the 1st index is the 
    value. We can use ES6 array destructuring to directly extract the values
    into separate variables.
