  • It absolutely should not have been named zeroth() because the reasoning for that is purely pedantic and ignores WHY arrays are 0 indexed. It’s not like the people in the early days of writing programming languages were saying “the zeroth item in the array” - they would refer to it using human language because they are humans, not machines. Arrays are 0 indexed because it’s more efficient for address location. To get the location in memory of an array item, it’s startingAddress + (objectSize * index). If they were 1 indexed, the machine would have to reverse the offset.
    Function/Method names, on the other hand, should be written so as to make the most sense to the humans reading and writing the code, because the humans are the only ones that care what the name is. When you have an array or list, it’s intuitive to think “I want the first thing in the array” or “I want the last thing in the array),” so it makes sense to use first and last. That also makes them intuitive counterparts (what would be the intuitive counterpart to “zeroth”?).

    Again, that’s incorrect. Pounds (Lbs) are the US measurement for mass. Feel free to provide a source to the contrary. I specified pounds mass vs pounds force because in an engineering space, it’s worthwhile to be specific, but the Pound (lb) is all that is specified in any documentation as the unit for mass in the US system.

    It’s just a pun. They’re both units of mass, hence there would be mass confusion.

    It doesn’t work with the pun, but the more confusing part for people would probably be the fact that pounds are used for both mass and force, but in SI, the units are different (kilograms for mass vs newtons for force), though that doesn’t really matter for most people.
