We can perform tasks based on conditions using if...else statements. They allow us to automate solutions to yes-or-no questions, also known as binary decisions.

In an if...else statement the if statement is used to decide whether or not to run a block of code. The else statement is used to run a block of code when the condition evaluates to false.

An else statement must be paired with an if statement, and together they are referred to as an if...else statement.

Example

let unsubscribed = true

if (unsubscribed) {
  console.log("We are sad to see you go!")
} else {
  console.log("Hope you are enjoying Codecademy!")
}

// We are sad to see you go!
