Part of the "fun" of JavaScript is dealing with code which comes from before sensible features existed. For example, if you wanted to clone an object in JavaScript, circa 2013, that was a wheel you needed to invent for yourself, as this StackOverflow thread highlights.

There are now better options, and you'd think that people would use them. However, the only thing more "fun" than dealing with code that hasn't caught up with the times is dealing with developers who haven't, and still insist on writing their own versions of standard methods.

Someone wanted to make sure that invalid routes logged an error in their Go web application. Artem found this when looking at production code.

Today's representative line comes from Capybara James (most recently previously). It's representative, not just of the code base, but of Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. Or, "you get what you measure".

If, for example, you decide that code coverage metrics are how you're going to judge developers, then your developers are going to ensure that the code coverage looks great. If you measure code coverage, then you will get code coverage- and nothing else.

Wolferitza sends us a large chunk of a C# class. We'll take it in chunks because there's a lot here, but let's start with the obvious problem:

    private int iID0;
    private int iID1;
    private int iID2;
    private int iID3;
    private int iID4;
    private int iID5;
    private int iID6;
    private int iID7;
    private int iID8;
    private int iID9;
    private int iID10;
    private int iID11;

    private int iID13;
