    Prefer do end while creating blocks in ruby

    We prefer using do..end instead of {} when using ruby blocks. {} is good when writing small one-liners or lambda, but using {} frequently makes code skewed as well as harder to read.

    1all_users.select {|user| user.is_admin? && user.is_team_member? && user.can_view_new_team_feature? }

    Now, let's see the do..end version:

    1all_users.select do |user|
    2  user.is_admin? && user.is_team_member? && user.can_view_new_team_feature?
    3end

    It's easier to read than the one-liner version, and can be further simplified as below:

    1all_users.select do |user|
    2  user.is_admin? &&
    3  user.is_team_member? &&
    4  user.can_view_new_team_feature?
    5end
