    Sure. And you’re entitled to yours. But words have meaning and this isn’t MY OPINION, it’s objective reality. It follows strict rules for predictable output, it is not nonsensical.

    You’re entitled to think it’s nonsense, and you’d be wrong. You don’t have to like implicit type coercion, but it’s popular and in many languages for good reason…

    Language Implicit Coercion Example
    JavaScript '5' - 1 → 4
    PHP '5' + 1 → 6
    Perl '5' + 1 → 6
    Bash $(( '5' + 1 )) → 6
    Lua "5" + 1 → 6
    R "5" + 1 → 6
    MATLAB '5' + 1 → 54 (ASCII math)
    SQL (MySQL) '5' + 1 → 6
    Visual Basic '5' + 1 → 6
    TypeScript '5' - 1 → 4
    Tcl "5" + 1 → 6
    Awk '5' + 1 → 6
    PowerShell '5' + 1 → 6
    ColdFusion '5' + 1 → 6
    VBScript '5' + 1 → 6
    ActionScript '5' - 1 → 4
    Objective-J '5' - 1 → 4
    Excel Formula "5" + 1 → 6
    PostScript (5) 1 add → 6

    I think JavaScript is filthy, I’m at home with C#, but I understand and don’t fear ITC.

        • In https://lemm.ee/comment/20947041 they claimed “implicit type coercion” and showed many examples; they did NOT claim “string concatenation”.
        • However, that was in reply to https://lemmy.world/comment/17473361 which was talking about “implicit conversion to string” which is a specific type of “implicit type coercion”; NONE of the examples given involved a conversion to string.
        • But also, that was in reply to https://lemm.ee/comment/20939144 which only mentions “implicit type coercion” in general.

        So, I think probably everyone in the thread is “correct”, but you are actually talking past one another.

        I think the JS behavior is a bad design choice, but it is well documented and consistent across implementations.
