What is the difference between nil and false in Ruby?

Answer 1

null means no data value but memory is still allocated for null. false is a boolean, it is simply not true.

Answer 2

" false is false, 0 is an integer, and nil is no value.
true is true, 1 is an integer, and nil is no value

Numbers, strings, and all other values evaluate to true.
nil evaluates to false. However, nil is not strictly equal to false, because false is a boolean datatype while nil has no datatype."

" The differences of the methods nil and false are:
- nil cannot be a value, where as a false can be a value
- A method returns true or false in case of a predicate, other wise nil is returned.
- false is a boolean data type, where as nil is not.
- nil is an object for NilClass, where as false is an object of for FalseClass
-False is a boolean datatype 
Nil is not a data type."
