if-else Statements

Kotlin uses the same if/else statement structure as most of the C-like languages and uses the same comparison operators.

val name = "Link"

if(name == "Link"){
  println("It's dangerous to go alone, take this!")
} else if (name == "Mario") {
  println("The Princess is in Another Castle.")
} else {
  println("Do a barrel roll!")
}

💡 Kotlin has the === and !== comparison operators, similar to Javascript. These operators evaluate based on reference

Conditional expression

A very nice feature of Kotlin language is to assign an if/else to a value.

val level = if(name == "Link") {
  5
} else {
  0
}

// You can omit the {}s when a branch contains one expression
val level = if(name == "Link") 5 else 0
