Increment variable in ruby [duplicate]
In Java, something like i++ would increment i by 1.
How can I do in Ruby? Surely there has to be a better way than i = i + 1?
From the documentation,
Ruby has no pre/post increment/decrement operator. For instance, x++ or x-- will fail to parse
So, you can do
i += 1
which is equivalent of i = i + 1
