Ruby and Rails
Ruby is the programming language. Rails is a framework written in Ruby. Rails runs on top of Ruby runtime.
Here are some example of ruby code:
puts "Hello world." # Hello world.
123.next # 124
[1, 2, 3].count # 3
[1, 2, 3] * 2 # [1, 2, 3, 1, 2, 3]
[1, 2, 3].reverse # [3, 2, 1]
variable_name = 30 # 30
puts "There are #{variable_name} cars." # There are 30 cars.
