[What do you call the -> operator in Ruby?](/questions/8476627/what-do-you- call-the-operator-in-ruby) (3 answers)
Closed 9 years ago.
In the following example:
default: -> { Time.now }
What's ->? I am familiar with => but first time I am seeing ->.
Answer
It's the Ruby 1.9 "stabby lambda" operator. For example, see this article from 2008.
Nutshell:
> foo2 = ->(arg) { arg * 2 }
> foo2.call "now"
=> nownow
Note the lack of space between -> and (arg), that's intentional.
