JavaScript if else

The if statement is used to run code based on a condition. You can extend it using else if and else to handle multiple conditions.

🔹 Example: Deciding what to wear based on temperature.

📌 Syntax

if (condition) {
  // code runs if condition is true
} else if (anotherCondition) {
  // code runs if anotherCondition is true
} else {
  // code runs if none are true
}

🔍 Real Example

let temp = 15;
if (temp > 30) {
  console.log("Wear a T-shirt");
} else if (temp > 20) {
  console.log("Wear a light jacket");
} else {
  console.log("Wear a coat");
}
