How to check Scala/Java in real Bytecode?

Imagine you have the following code in  AntiTailRecursive.scala

object bc {

  def factorial(n: BigInt): BigInt = {
    if (n == 0)
      1
    else {
      //n*factorial(n-1)
      val t1 = n - 1
      val t2 = factorial(t1)
      n * t2
    }
  }

  def main(args: Array[String]): Unit = {
    println(factorial(5))

  }
}

$ scalac AntiTailRecursive.scala  #compile the code
$ scala b # verify that the code works
$ javap -l -p -c -v b     #To view the java byte code of this scala source code/class:

Peer-to-Peer Command-Line Chat in Go Lang

Some notes :

1. Spent quite some time on finding and setting up debuggers
