Example:

let age = 20;
let hasID = true;

if (age >= 18 && hasID) {
  console.log("Access granted.");
} else {
  console.log("Access denied.");
}
// Output: "Access granted."

• Create variables a and b with values 12 and 4.
• Perform all arithmetic operations and log the results.

     let a = 12;
     let b = 4;
     console.log("Addition:", a + b);        // 16
     console.log("Subtraction:", a - b);     // 8
     console.log("Multiplication:", a * b);  // 48
     console.log("Division:", a / b);        // 3
     console.log("Modulus:", a % b);         // 0

  const add = function (a, b) {
    return a + b;
  };
  console.log(add(3, 5)); // 8

• Arrow Functions (ES6):

    console.log(10 / 0); // Infinity

• NaN: Result of an invalid number operation.

     var message = "Hello, World!";
     console.log(message);

• Preferred for declaring variables that can change value.
