Controller Action to create pages: What does "render text:", do exactly? And what is "params"?

Is "params" a variable that was defined earlier in the coarse or its a built in method? And if so what does it do?

render is a method defined on all controllers. It uses variables defined in your code to create a response to send back to the user's browser. Depending on its arguments, it can render plain text, an ERB template (which usually contains HTML), or other things. The text: argument specifies a plain string that it should render.

params is also a method defined on all controllers. It returns a hash-like object containing any URL parameters or form field contents submitted by the user's browser.
