  • Coming to grips with JS: a Rubyist's deep dive
    16 projects | dev.to | 29 Dec 2023
    Note, however, that there is a proposal to add pattern matching to JS.
  • Level up your Typescript game, functionally - Part 2
    2 projects | dev.to | 25 Nov 2023
    There's an ECMAScript proposal that is in the works to add this feature to the language! It's going to look something like this.
  • Building React Components Using Unions in TypeScript

    More importantly, TypeScript typically commits to build things into itself when the proposal in JavaScript reaches Stage 3. The pattern matching proposal in JavaScript is Stage 1, but depends on many other proposals as well that may or may not need to be at Stage 3 as well for it to work. This particular proposal is interested on pattern matching on JavaScript Objects and other primitives, just like Python does with it’s native primitives. These are also dynamic types which helps in some areas, but makes it harder than others. Additionally, the JavaScript type annotations proposal needs to possibly account for this. So it’s going to be awhile. Like many years.
  • Explicit Software Design. Preliminary Conclusions
    3 projects | dev.to | 18 Sep 2023
    For true™ functional programming in JS, native pattern matching and partial function application are missing (at least for now: 1, 2). For proper OOP, it lacks real interfaces and compile-time dependency injection.
  • TypeScript Is Surprisingly OK for Compilers
    14 projects | news.ycombinator.com | 18 Aug 2023
    The proposal for pattern matching syntax seems more akin to what they're looking for.

  • [AskJS] C# in every Node.js job posting?
    2 projects | /r/javascript | 7 Jun 2023
    There's a proposal to add something like that to JavaScript but it's been stuck in limbo since 2017 although there are libraries like ts-pattern which implement it already.
  • [AskTS] What do you think will be the future of runtime type checking?
    10 projects | /r/typescript | 28 May 2023
    I'll admit, it is easy to assert that the TypeScript language should not be involved in the matters of packages but I also wonder if we're moving towards a point where interfaces will be as common as namespaces and whether or not it would be sensible for the language to incorporate such type assertions into the language formally, after all, it already compiles to various forms of JavaScript and there is a stage 1 proposal submitted to the TC39 committee to give JavaScript pattern matching. If adopted, wouldn't it make sense to allow TypeScript to compile a type into a type guard for the native JavaScript pattern matcher?
  • Updates from the 96th TC39 meeting
    5 projects | /r/javascript | 19 May 2023
  • Mostly adequate guide to FP (in JavaScript)
    5 projects | news.ycombinator.com | 21 Mar 2023
    Both are active tc39 proposals :)

    https://github.com/tc39/proposal-pipeline-operator - Stage 2

    https://github.com/tc39/proposal-pattern-matching - Stage 1

    Hopefully we get both in the next couple of years.

  • CoffeeScript for TypeScript
    5 projects | news.ycombinator.com | 27 Feb 2023
    We often add promising TC39 proposals into Civet so people can experiment without waiting.

    We've added https://github.com/tc39/proposal-pipeline-operator, a variant of https://github.com/tc39/proposal-pattern-matching, a variant of https://github.com/tc39/proposal-string-dedent and others.

    Since our goal is to be 99% compatible with ES we'll need to accommodate any proposals that become standard and pick up anything TC39 leaves on the table (rest parameters in any position, etc.)
