📘 Day 35: Conditional Statements in JavaScript

📘 Day 35: Conditional Statements in JavaScript

Conditional statements allow your program to make decisions based on certain conditions. They help you control the flow of execution, so different code runs in different situations.

🔹 Types of Conditional Statements

  • if statement – Runs a block if the condition is true.
  • if...else statement – Runs one block if true, another if false.
  • if...else if...else ladder – Tests multiple conditions in sequence.
  • switch statement – Executes one case among many choices.

🧠 Example 1: if statement

let age = 18;
if (age >= 18) {
  console.log("You are eligible to vote!");
}

🧠 Example 2: if...else statement

let number = 10;
if (number % 2 === 0) {
  console.log("Even number");
} else {
  console.log("Odd number");
}

🧠 Example 3: if...else if...else ladder

let marks = 85;
if (marks >= 90) {
  console.log("Grade: A+");
} else if (marks >= 75) {
  console.log("Grade: A");
} else if (marks >= 60) {
  console.log("Grade: B");
} else {
  console.log("Grade: C");
}

🧠 Example 4: switch statement

let day = "Monday";

switch(day) {
  case "Monday":
    console.log("Start your week strong!");
    break;
  case "Friday":
    console.log("Weekend is almost here!");
    break;
  default:
    console.log("Enjoy your day!");
}

✅ Practice Task
