 ### Explanations
 
 Since both a and b are defined within the enclosing scope of the function, and since the line they are on begins with the var keyword, most JavaScript developers would expect typeof a and typeof b to both be undefined in the above example.
 
 However, that is not the case. The issue here is that most developers incorrectly understand the statement var a = b = 3; to be shorthand for:

 But in fact, var a = b = 3; is actually shorthand for:

 As a result (if you are not using strict mode), the output of the code snippet would be:

 But how can b be defined outside of the scope of the enclosing function? Well, since the statement var a = b = 3; is shorthand for the statements b = 3; and var a = b;, b ends up being a global variable (since it is not preceded by the var keyword) and is therefore still in scope even outside of the enclosing function.
