What is the value of "result" after executing the following ...
The "multiplyByTwo" function takes a number and returns an anonymous function. The anonymous function logs the value of the "result" variable, which is the input number multiplied by 2. When "multiplyByTwoFn" is invoked, it calls the returned anonymous function and outputs the value of "result", which is 10.
