How to work with respond_to?
How do you work with it?
string = String.new("a random string") String = respond_to?.upcase
Use dot notation to chain
respond_to? onto the
string variable (lowercase s). Then pass in the method (
upcase) either as a symbol,
:upcase or as a string,
#symbol uses a preceding colon string.respond_to? :upcase # or string.respond_to?("upcase") # parentheses optional
I hope that helps,
