Speaking of pushing to arrays, Ruby has some nice shortcuts for common method names. As luck would have it, one is for .push
!
Instead of typing out the .push
method name, you can simply use <<
, the concatenation operator (also known as “the shovel”) to add an element to the end of an array:
[1, 2, 3] << 4 # ==> [1, 2, 3, 4]
Good news: it also works on strings! You can do:
"Yukihiro " << "Matsumoto" # ==> "Yukihiro Matsumoto"
