🚦 Lesson 4: Control Flow (Decision Making)
⏱️ Estimated time: 25 minutes | Difficulty: Beginner
Conditional Logic
Control flow allows your program to execute different pieces of code depending on whether a condition is true or false.
Arithmetic Operators
let a = 10, b = 3;
console.log(a + b); // 13 (addition)
console.log(a - b); // 7 (subtraction)
console.log(a * b); // 30 (multiplication)
console.log(a / b); // 3.333... (division)
console.log(a % b); // 1 (remainder)
console.log(a ** b); // 1000 (exponentiation)Comparison Operators
console.log(5 == 5); // true
console.log(5 === "5"); // false (different types)
console.log(5 != 3); // true
console.log(5 > 3); // true
console.log(5 < 3); // false
console.log(5 >= 5); // trueLogical Operators
let isStudent = true;
let hasID = true;
console.log(isStudent && hasID); // true (AND)
console.log(isStudent || false); // true (OR)
console.log(!isStudent); // false (NOT)
