Advanced Functional Programming with Scala - Notes

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

	#!/usr/bin/env bash

	: "${SLACK_API_TOKEN:?Need to set SLACK_API_TOKEN environment variable}"

	STATUS=$(/usr/bin/osascript <<"EOF"

	tell application "Spotify"
	set currentArtist to artist of current track as string
	set currentSong to name of current track as string
	return currentArtist & " - " & currentSong

	class MyClass:

	def __init__(self, a, b, c):
	self.value_1 = a
	self.value_2 = b
	self.value_3 = c

	def __iter__(self):
	""" enables dict(object) functionality """
	yield "key1", self.value_1

	def identity_print(x):
	print(x)
	return x

	echo_FP = lambda: identity_print(input("FP -- "))=='quit' or echo_FP()

	echo_FP()

	handler.setFormatter(formatter)
	logger.addHandler(handler)
	logger.setLevel(logging.DEBUG)

	logger.debug("Testing, testing, 1, 2, 3")

	case x if Assembly.isConfigFile(x) =>
