First Class Functions

Classes are nouns
Methods are verbs
Functions are gerunds
Kotlin has first class functions
These replace the need for static methods


fun bigDecimalEquals(
    one: BigDecimal, 
    two: BigDecimal) : Boolean { 
  return one.compareTo(two) == 0
}


fun bigDecimalEquals(
    one: BigDecimal, 
    two: BigDecimal) : Boolean = one.compareTo(two) == 0


val bigDecimalEquals: Boolean = one.compareTo(two) == 0
