If, Else

In the previous exercise, we wrote an if statement that executes some code if its condition is true. However, we often need to do something if the condition is false. For this, we use the else statement. For example:

let age = 15;
if (age > 17) { // if age is greater than 17, execute:
	console.log("You can enter");
}
else { // otherwise, execute:
	console.log("You cannot enter");
}
// Prints: You cannot enter

In the example, you can see that if age is greater than 17, it prints You can enter. Otherwise (if age is less than or equal to 17), it prints You cannot enter.
