Aprende Challenge: Modify and Extend an Object | Fundamentals of JavaScript Objects

Task

You're given an object, student, representing a student's information. Your task is to modify existing properties and add new properties.

Modify the student's age to be 21.
Add a new property called grade and set it to "A".


              12345678910111213
            
const student = {
  name: "Pauline Reilly",
  age: 24,
  major: "Humanities",
};

// Task 1: Modify `age` to `21`
___ = ___
console.log(student.age); // Output: 21

// Task 2: Add a new property `grade`
___ = ___
console.log(student.grade); // Output: A

Expected output:

21
A

To modify a property's value, use assignment with dot notation.
To add a new property, use the assignment with dot notation, providing the property name and value.


              12345678910111213
            
const student = {
  name: "Pauline Reilly",
  age: 24,
  major: "Humanities",
};

// Task 1: Modify `age` to `21`
student.age = 21;
console.log(student.age); // Output: 21

// Task 2: Add a new property `grade`
student.grade = "A";
console.log(student.grade); // Output: A
