I have array
numbers = [ 1, 2, 3, 4, 5, 6 ]
I have a variable:
number = 4
I want with a loop for or each block return false unless the number 4 for this case exist in array.
numbers.each do |number_loop|
return false unless number_loop == number
end
But I get an error:
LocalJumpError: unexpected return from (irb):25:in `block in irb_binding'
Unless you're doing something else in the block that you've hidden from posting here, why don't you just do:
return false if numbers.include? number
As for the reason you get a LocalJumpError there: if your code isn't in a method then there isn't anything to return to (or, put another way: nothing to jump back to). In that case you're probably trying to set a variable rather than return, and you'd want to do:
is_included = numbers.include? number
Try with :
numbers.include?(number)
It should work.
As others have mentioned you should use #include? to check for inclusion. Also take a look at #any? and #all? which can be used to check whether any or all elements in a collection match a certain block.
