You can provide a second part to the if statement: else.

You attach a statement that is going to be executed if the if condition is false:

if (true) {
  //do something
} else {
  //do something else
}

Since else accepts a statement, you can nest another if/else statement inside it:

if (a === true) {
  //do something
} else if (b === true) {
  //do something else
} else {
  //fallback
}
