    Intro to Recursion - Refactoring to a Pure Function

    Shane OsbourneShane Osbourne

    Our previous solution used forEach and a globally available array that could be mutated from inside our function. We can improve upon this and create a function that is easier to maintain & test by swapping our forEach loop for reduce. By removing the global array and instead making getTasks return a value directly we end up with a pure function.
