An alternative DSL proposal for JavaScript

Please direct all comments to this issue. I won't receive notifications if you comment here, but I will receive them if you comment there.

A DSL proposal for JavaScript

This is an attempt to create a more cohesive, easy-to-implement DSL proposal for JavaScript, attempting to work around most of the issues described in this original proposal. Of course, this is pretty poorly formatted and it's missing a few edge cases, but it's just a strawman.

Syntax

  • Blocks close over environment, but have phantom @@this context (syntax error outside DSL)
  • @foo(...) do { ... } - Invoke @@this.foo(..., block)

Simple date library
// A simpler implementation of date handling, with the following additional

// 1. We only need the day, month, and year.
// 2. Time zones are irrelevant.
// 3. Day/month/year checks and range checks are *far* more common than date
// difference calculation.
// 4. Dates are rarely written to, mostly read.
//
// Helpfully, this lets us represent dates with a single 32-bit integer, which

JS pattern matching strawman

Note: if you wish to comment on this proposal, tell me here, so I can actually be notified.

JS Pattern Matching Strawman

Just an attempt to come up with a sane pattern matching proposal that doesn't hit any of the following pitfalls:

  • Unidiomatic - if it doesn't look at all like JS, not very many will want to try it.
  • Prohibitively slow - if it can't be made fast, implementors are going to question it and users will complain.

TypeScript Constraint Types Proposal

(All feedback/discussion should take place in the relevant issue.)

TypeScript Constraint Types Proposal

There's multiple requests for the ability to control a type at a much more fine grained level:

  • #12424: Mapped conditional types
  • #12885: Typing function overloads
  • #12880: Bad inference for lambda closures
  • Promises wrongfully accept thenables as their generic parameter (thenables can never be the argument to a then callback).
