Hi out there,
after looking at rails and the pickaxe book (not totally red yet, just
used as a reference) I still wondering when to use just a construct
:a => something
What does it stands for and when to use it? Please apologize if it’s a
basic questions, but I can’t realize myself the usage.
If someone has a page no. in the pickaxe book, I’m glad to read the
Thanks in advance.
