State built up before a loop is lost

8

```js (function () { var n = __abstract('number', '(5)'); var arr = {0: 'a', 1: 'b'}; var i = 2; do { arr[i] = 'x'; i++; } while(i < n);...

Does Simple Assume Partial?

2

```js var c = __abstract('boolean', 'c'); var y = __abstract('object', 'y'); __makeSimple(y); var obj = Object.assign({}, y); has = 'anything' in obj; desc = Object.getOwnPropertyDescriptor(obj, 'anything'); ``` This doesn't define...

ObjectValue has optional fields which isn't supported

2

Flow doesn't support optional field in classes. Internally, we transpile using the class fields transform which turns all Flow annotated fields into field initializers with `undefined`. So ObjectValue turns into...

```js (function () { var key = __abstract('string', '("y")'); function Foo() { } Foo.prototype.x = function() { }; var obj = new Foo(); obj[key] = 123; result = typeof obj.x...

"Empty" Values Behave Strangely with getOwnPropertyDescriptor

1

```js var c = __abstract('boolean', 'c'); var x = {foo:1}; if (c) x.bar = 2; result2 = Object.getOwnPropertyDescriptor(x, 'bar'); var y = __abstract({foo:1}, 'y'); __makeSimple(y); if (c) y.bar = 2;...

Idiomatic Way to Explicitly Tell an Underlying Transform Stream to Flush to the Sink

12

Sometimes transform streams keep some internal state and keeps a buffer window. It then waits to flush that buffer to the readable stream until the buffer window is full. Examples...

[Flight] Implement FlightClient in terms of Thenable/Promises instead of throwing Promises

1

This moves the Flight Client's to use Chunks that mimick a variant of Promises instead of relying on throwing Promises. It still throws Promises in the bounds (readRoot and the...

Consider Special Casing Certain DOM Attributes to Accept Elements

1

The use case is for example, translation components rendering string content. The HTML spec has some unfortunate attributes that behave kind of like content. It seems like they should be...

Support All of Structure Clone in RSC Serialization

10

The React Server Components payload is a custom protocol that extends what is serializable beyond just JSON. Beyond just JSON we also support all React primitives (React.lazy, ReactNode) and global...
