Usually that effort should go toward naming functions rather than their results, though, and if the functions have good names, the results don't need them. In this example, `other_function` could have been named `get_user_data`, `new_function` could have been called `extract_user_details`, whatever.

Once you have good function names, which you should generally be spending a lot more effort on than good local variable names, you won't find any value in adding variables like `var foo = get_foo()`.
