This cop looks for inject / reduce calls where the passed in object is returned at the end and so could be replace by each_with_object without the need to return the object at the end.
@example
# bad [1, 2].inject({}) { |a, e| a[e] = e; a } # good [1, 2].each_with_object({}) { |e, a| a[e] = e }
# File lib/rubocop/cop/style/each_with_object.rb, line 19 def on_block(node) method, args, body = *node _, method_name, method_args = *method return unless METHODS.include? method_name return if method_args.type == :sym return_value = return_value(body) return unless return_value return unless first_argument_returned?(args, return_value) add_offense(method, :selector, format(MSG, method_name)) end
