Mojo Lingo / Adhearsion Code Style Guide

Ruby is very flexible and will allow you to butcher all of the good things about its syntax in a large variety of ways. Here we'll present, by example, how to keep things nice.

Parentheses

Bad

foo.bar(a)

Good

# Write a program that prints the numbers from 1 to 100. 
# But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz".
# For numbers which are multiples of both three and five print "FizzBuzz".


(1..100).each do |i|
  res = if i % 3 == 0 && i % 5 == 0
    "FizzBuzz"
