The split method presents a particular use case when we need to cut on spaces. Explicitly specifying " " as an argument will not produce the expected result 🤯. The solution is to use a regex / /.
We can trace the history back to the beginning of Ruby on git in 1996 with this comment on this line (and discover at the same time that he took a tour on SVN).
We have selected 2 other interesting uses. It can take a block as an argument, allowing you to iterate directly on the result, thus avoiding an intermediate array.
The cutting pattern can be maintained with groups.
