  • "1" + 2 === "12" is not unique to JS (sans the requirement for the third equals sign), it’s a common feature of multiple strongly typed languages. imho it’s fine.

    EDIT: I did some testing:

    What it works in:

    • JS
    • TS
    • Java
    • C#
    • C++
    • Kotlin
    • Groovy
    • Scala
    • PowerShell

    What produces a number, instead of a string:

    • PHP
    • SQL
    • Perl
    • VB
    • Lua

    What it doesn’t work in:

    • R
    • C
    • Go
    • Swift
    • Rust
    • Python
    • Pascal
    • Ruby
    • Objective C
    • Julia
    • Fortran
    • Ada
    • Dart
    • D
    • Elixir

    And MATLAB appears to produce 51, wtf idk



  • Usually they’re building the website with browserlist and polyfills, and they specify how old a browser they wish to support, usually by analysing percentages of public usage, or they allow types only supported in newer browsers. Meaning if they use a feature only available in newer browsers, then it won’t be automatically backported to support older browsers.

    But that’s only if they actually use those features, they’re just available to them. And it’ll only break in those places they do use them, which could be quite little of the site.

    So often it’s just “we can’t guarantee it’ll work in your old browser and enough of our users use newer browsers that we’ll block you and not care”.




  • Unless everybody fully customises the display and styling of the adverts for their own website, there’s going to be some sort of targetable, recognisable pattern in the way AdSense content looks. Most developers just want an easy drop-in solution.

    Furthermore, Google don’t necessarily want to give you that level of control over the adverts, because that makes it easier to game the ads system with malicious, fake and misleading clicks or invisible adverts. They need their tracking tech attached to it.
