Is there a clear advantage to declaring a variable inside a function that gets the content of the function and then returning that variable vs writing return before the content of the function and not declaring any variable?
Am I correct in assuming the second method will work fine in a simple function, where declaring variables within a function is necessary when the function is more complicated?
Thanks in advance!
