    1. You can call it “Java” to enrage other programmers
    2. You can compare numbers against strings without wasting time converting them

        JavaScript: :wide eyed and smiling: Sure why not! You’re the boss!

        Python: Sighing and downing half a bottle of Advil: Sure. Why not, you’re the boss.

      If you’re living in 2002 and not using the strict equality operator, that’s on you

        But what if I don’t want strict comparison? What if my frontend contains a text field for a numeric input and I wanna manually check against each possible valid input value if (input_val == 1) {...} else if (input_val == 2) {...} else if... without having to convert it first or check that it’s actually a number or fix my frontend?

        (I’m sure there are valid use cases for non-strict comparison, I just can’t think of one right now)

          why wouldn’t you just convert inline? (Number(input_val) === 2)

          Converting would mean you could use a switch statement with your example rather than an if else ladder

          switch(Number(input_val)) {
            case 1:
              doTheFirstThing();
            break;
            case 2:
              doTheSecondThing();
            break;
            case 3:
              doTheThirdThing();
            break;
          }

            If you’re looking for good code, you missed the point of my comment 😄

            If I was looking for an enumeration of valid inputs, I’d make it a selection box rather than a text field that’s supposed to contain a number and give the selections reasonable names. If I want an integral quantity, I’d use a number input field.

            If I have no control over the frontend, that means I’m writing a backend in JS for a bullshit frontend, and no amount of good coding practice is going to salvage this mess.

            I’m also blessedly far away from WebDev now. I work in Data Analytics and if I ever have to do any of this for a living, something has gone very wrong.

            Converting texts into numbers or dates still haunts me though - fuck text inputs for numbers and dates.
