What will be the result of the following code?
 function myFunction() {
    var a = 1;
    if ( a == 1 ) {
        var b = 2;
    }
    return b;
}
myFunction();
 
Explanation
In JavaScript 'var' declares the variable inside the scope of the function.

As the function is not called, there is no result...
