Is "Javascript" a case sensitive language ?

Is "Javascript" a case sensitive language ?

Select from following answers:

1. No
2. Yes
3. Maybe

Yes, "Javascript" is a case sensitive language.
For example,

var myname = "sekhar";

var Myname = "sekhar";

The above variables are treated as differently ! 

What is the difference between the below two statements:-
(1) var myname = "Akiii";
(2) myname = "Akiii";

Answer:

Both the above two statements are same. In javascript, even if you don't declare a "var" keyword, it is automatically added.

Note:-
It is always good to use "var" to declare any variable in javascript. It makes the code cleaner and readable.
