if, else if, else

The if, else if, and else statements are used for decision-making in JavaScript.

• if: Executes a block of code if the condition is true.
• else if: Tests additional conditions if the previous conditions are false.
• else: Executes a block of code if none of the previous conditions are true.

Example:

let age = 20;

if (age < 18) {
  console.log("You are a minor.");
} else if (age < 60) {
  console.log("You are an adult.");
} else {
  console.log("You are a senior citizen.");
}
