Sandra, still at InitAg, has to work with Brad. Some time ago, Brad was assigned a slew of front-end development tasks, since he’s a web developer. But Brad isn’t a front-end developer, and doesn’t really have a good grasp of front-end development. Management isn’t clear on the difference: “Aren’t you a web developer? I don’t care which end you use, just develop.” Brad is also game to tackle whatever task is assigned to him, regardless of whether he has any sense of how to solve the problem.
When Brad needed to display data on a map, the requirements wanted the map layers to be distinguished by color. So Brad did the usual thing one might do in this situation: he created a gigantic array of all possible colors that might be used on the map. Actually, he created two: colors and colorsBlackWhite.
let colorsBlackWhite = ["#000000", "#010101", "#020202", "#030303", "#040404", "#050505", "#060606", "#070707", "#080808", "#090909",

Whitespace added so it’s not a single line of every possible grey.
That’s just the black-and-white array. 255 shades of grey. This is used as a lookup table, where a layer’s index determines what color it gets. That doesn’t seem like a great way to manage that, especially since it means adjacent layers are going to have adjacent colors.
The arrays were used like this:
colorUsed = colors[idx];
{% if is_granted('ROLE_UBER') or _user.email == '[email protected]' %}
colorUsed = colorsBlackWhite[idx];
{% endif %}
Note the mix of PHP and JavaScript- as mentioned, Brad wasn’t a front-end developer, so he used the back-end tool he knew. Everyone gets a color map, unless they’re a ROLE_UBER or have a very specific, hard-coded email address. Those people get a black-and-white map.
Or at least they used to. In late 2021, Brad removed the usage of the colorsBlackWhite array (but not the array itself) in one gigantic mega-commit that alter a few thousand lines of code in the application, with the commit comment: “Code cleanup.”
