  • The dangers of single line regular expressions
    1 project | news.ycombinator.com | 22 Apr 2024
    `$` does mean end of input in Java, unless you explicitly ask for multiline mode. In the latter case it means `(?=$|\n)` if also in Unix-lines mode, and the horrible `(?=$|(?I wrote a compiler from Java regex to JavaScript RegExp, in which you'll find that particular compilation scheme [1].

    > Scala choices were directly dictated by JVM

    Initially, yes. But Scala has evolved beyond the JVM, with Scala.js [1] being rock-solid, and Scala Native [2] under development. Neither are truly hampered by the initial JVM roots of Scala.

    Weird analogy ;)

    What does that have to do with language size? It also compiles to js https://www.scala-js.org/ and native https://scala-native.org/en/stable/

    Here's a hybrid option: Scala.js. Yes, it is about building web applications but in Scala. You can retain the HTML/CSS/JS knowledge you have but build web applications from a typesafe and powerful language: Scala
  • Dropping Scala 2.11 support in Scala.js and Scala Native
    3 projects | /r/scala | 6 Dec 2022
    The compiler crash in question affects another feature that we would like to merge for the benefit of all users, namely https://github.com/scala-js/scala-js/pull/4735. Keeping 2.11 means that testing and shipping that feature is much more difficult, even for 2.12+ users only. It's not just "to fix a compiler crash".

    TS is more in the "mixed feelings" department, imho.

    I would take Scala.js anytime instead. (If I would need to do front-end ever again).
