67. if

The code will output:

BFE
Uncaught ReferenceError: bar is not defined

The if (true) block will be executed, which declares and defines the foo() function. The if (false) block is not executed, so the bar() function is not declared or defined.

When foo() is called, it will print "BFE" to the console.

When bar() is called, it will result in a ReferenceError because bar is not defined.
