What is the difference between these two params?

Question

I'm a beginner in rails, I want to know what is the diiference between these two:

params["user_id"]

and

params[:user_id]

Answer 1

In first call, you pass string to [] method, in secod, you pass symbol. Since params returns HashWithIndifferentAccess instance, there's no difference in returned object.
