Scala Method Notations

Infix Notation/Operator Notation
Method with one parameter can be accessed with space (Natural Language)

class Person {
  def sayHello(name: String) = println(s"Hello $name")
val person = new Person
person sayHello "Niranjan"

In scala we can also use +/-/*/#/$ as method names which makes it much more comfortable to code with unlike other languages. This is exactly what is happening in mathematical operators as they are also methods

    println(1 + 3)

PREFIX NOTATION or Unary Operator
A Unary Operator is also a METHOD in SCALA
All UNARY Operators are methods with prefix “unary_”

val x = -1
// Its same as
val y = 1.unary_-

POSTFIX Notation
Method with no parameter can be accessed without paranthesis

class Person {
  def sayHello = println("Hello")
val person = new Person
// OR
person sayHello
