What is terms of memory allocation?
Let a = null;
means that memory is allocated to variable "a" and a value null is assigned to it.
But in case of
Let b;
Memory is allocated for variable "b" and nothing is explicitly assigned to it as a value so javascript assign undefined to it

Please tell me if I'm right or wrong
