lesson 2 notes

// Scala Functions

def isPrime(natNum:Int): Boolean = {
	asdf
}

inside paren is variable types and outside is the return type
analogue is public boolean isPrime

=====

// Variables

var name:String = "tom"
val name:String = "tom"

var can be reassigned but val cannot-- different from being immutable
val my_array = Array(1,2,3,4)
cannot do my_array = my_array2
but you can do my_array(3) = 17
