  • Nice writeup, and well put.

    Another point that I would have made is: often, novices structure code in weird ways, with procedures that aren’t very useful outside the context in which they were conceived because they are big and do too many things. They use variables that get recycled over too many intermediate calculations, or conversely fail to break calculations into intermediate steps saved in variables.

    Naming is a good detector for such problems. If you can’t think of a good precise name

    • When I name an array after the objects it contains, I don't know whether to use the plural, or the singular, ie whether to call it objects, or object.

      @persons means I start saying $persons[0], $persons[2]. @person reads nicer when referring to the elements, $person[1], $person[2].

      But the second might confuse a reader of the code?
