Re: how many diffrent between ruby 1.8 vs 2.3?

I recommend you to find a newer book. Ruby had important changes from version 1.8 to 1.9, including new syntax.

A couple of things I can think of:

* This is valid syntax in 1.9 but not in 1.8: {a: 'value', b: 'value'}.
* This is a valid method definition in 1.9 but not in 1.8:

```
def method argument
  # stuff
end
```
