29. Hoisting III

The code below outputs:

2
2
1

Explanation:

• Inside the func function, the a variable is shadowed by the declared var a variable. Therefore, when a is reassigned to 2, it only affects the local a variable, not the global one. The first console.log outputs 2.
• After calling func(), the value of the global a variable has not changed, so the second console.log outputs 1.
• The if condition evaluates to true since the global object (window) does not have a property named b. The var b = 1 declaration then creates a global b variable with the value 1. The last console.log outputs 1.
