If I wanted to do something like this:
collection.each do |i|
return nil if i == 3
..many lines of code here..
end
How would I get that effect? I know I could just wrap everything inside the block in a big if statement, but I'd like to avoid the nesting if possible.
Break would not work here, because I do not want to stop iteration of the remaining elements.
next
inside a block returns from the block. break
inside a block returns from the function that yielded to the block. For each
this means that break
exits the loop and next
jumps to the next iteration of the loop (thus the names). You can return values with next value
and break value
.
