I'm only just starting to learn Ruby, but this seems wrong:

"We also can view a subset of the original array by passing two indexes separated by a comma, indicating the first and last index that we want:


Shouldn't it be "indicating the first index and the LENGTH OF THE SUBSTRING that we want"?

Nice and fast intro (plus two typos)

I enjoyed this fast intro to Ruby, which quickly points out the basics with nice and clear examples for anyone with some programming experience to easily go hands-on.

I did notice these two typos:

1. When you mention string conversion methods, it is written "You can convert a string to an integer or float using the to_i and to_s methods", but I believe you meant "to_i and to_f"

2. When you give the "id_squared" method example, you mention in the explaining paragraph that it "returns its doubled value", where it should be the "squared value"

Regardless of this, I did enjoy reading this intro.
