Tutorials Programming Tutorials, Guides & Best Practices

• The user must be logged in (isLoggedIn is true).
• The user's account must not be suspended (isSuspended is false).

let number = 12;
if (number > 10 && number % 2 === 0) {
  console.log("The number is greater than 10 and even.");
}

let isLoggedIn = true;
let isSuspended = false;

if (isLoggedIn && !isSuspended) {
  console.log("User can log in.");
} else {
  console.log("Access denied.");
}

• Adds two numbers.
• Example:

     let sum = 10 + 5; // 15

  let person = {
    name: "Alice",
    age: 25,
    isStudent: true,
  };

• Accessing Properties:
• Dot notation:

• Your name (string).
• Your age (number).
• Whether you are a student (boolean).

Example:

• Used in older JavaScript versions but largely replaced by let and const.
• Example:

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