💡 Tip of the Week

Anonymous Block Forwarding

Many of us have likely read or written Ruby code that takes a block argument and delegates it straight to another method. For example:

def some_method(&block)

We name a block argument &block (or something similar) just to forward that &block argument to another method.

Last year's Ruby 3.1 release introduced anonymous block forwarding when the argument is being passed to another method. This means that as of Ruby 3.1, you no longed need to name the block parameter and can instead use &. Our example above becomes:

def some_method(&)

If you're interested in adopting (or avoiding!) this style into your codebase, there's already a RuboCop cop for it!
