ES6 Destructuring

const student = {
    name: 'John Doe',
    age: 16,
    scores: {
        maths: 74,
        english: 63
    }
};

// We define 3 local variables: name, maths, science
const { name, scores: {maths, science = 50} } = student;


const person = {
    name: 'John Doe',
    country: 'Canada'
};

// Assign default value of 25 to years if age key is undefined
const { name: fullname, country: place, age: years = 25 } = person;

// Here I am using ES6 template literals
console.log(`I am ${fullname} from ${place} and I am ${years} years old.`);
