Many years ago, I took part in the development of a taxi-hailing mobile app that is still widely used today. I don’t know what kind of code they’re running now, but in those early days, the driver assignment code –if I remember it correctly– was similar in spirit to the grossly simplified example that follows. There are five levels of nested if statements in less than 30 lines of code. It doesn’t look so bad, some might say, but it’s not difficult to imagine how complicated this code can become with just a few more checks…

    Sometimes is it worth to rethink the problem. Especially when your condition is based on set-members. Using quantor logic often simplifies the condition :

    return 
    any(x for x in X if x==condition_a) 
    or all(y for y in Y if y==condition_b) 
    and all(x for x in X if x==condition_c)

    I am not sure if JS has something similar, but this often helps by a lot

      It does, the some/every array methods would achieve the same results. I use them quite often myself!
