Task 1: Declare Variables

- Create 3 variables using let, const, and var.
- Store your age in one,
- Your name in another,
- The value of Pi (3.1416) in the last one.

Task 2: Work with Data Types

- Create variables for different data types:
  • A number (e.g., let score = 100;)
  • A string (e.g., let greeting = "Hello!";)
  • A boolean (e.g., let isStudent = true;)
- Print all of them using console.log().

Task 3: Perform Basic Operations

- Add two numbers (e.g., 10 + 20) and print the result.
- Concatenate two strings (your first name + last name).
- Compare two numbers (5 > 3, 10 == "10", etc.) and print the results.
- Use logical operators:
  • true && false
  • true || false
  • !true

Task 4: Small Challenge

Write a small program that:
- Stores your name and age in variables.
- Prints: "Hi, my name is [YourName] and I am [YourAge] years old."
(Hint: use string concatenation or template literals `Hi, my name is ${name}...`)

By completing this assignment, you’ll practice declaring variables, using data types, and applying operations — everything we covered today.

Create an array of numbers. Use the `map()` method to double each number, and then use the `filter()` method to keep only the even numbers. Finally, use a loop to print the resulting array.
