@jakebailey, I have made local WIP improvements for nested patterns. However, there are some pre-existing inconsistencies between array and binding patterns. It would be great if we could establish the desired behavior as that heavily impacts how I should implement this. Let's take a look at this (TS 5.5 playground):

function testObj({ a, b, c = 1 } = { a: 2 }) {} // implicit any on `b`, ok

testObj({ a: 3 }); // error, missing `b`

function testArr([a, b, c = 1] = [2]) {} // implicit any on `b`, ok

testArr([3]); // no error

As we can see above, the optionality is different for those members with inferred implicit anys

It might be easier to make those properties optional if we don't want to revert parts of #59183 . the parts mentioned there as "strictly not necessary for the fix"

Looks like you're introducing a change to the public API surface area. If this includes breaking changes, please document them on our wiki's API Breaking Changes page.

Also, please make sure @DanielRosenwasser and @RyanCavanaugh are aware of the changes, just as a heads up.

Andarist · 2024-09-14T07:31:38Z

I pushed out changes to make those members with inferred implicit anys optional. Today they must be optional because the initializer's type is no longer "padded" (since #59183 ).

Given this example:

// @strict: true
function test({ a } = {}) {}

We get {} as the initializer's type and the initializer's type is checked if it's assignable to the parameter type. So if we infer { a: any } we get 2 errors:

an implicit any is reported on the a binding element
we get an error that {} is missing a required a property

This doesn't feel right. So I've decided to make those implicit anys optional. This allows the non-padded initializer's type to stay assignable to the padded parameter type.

Based on my previous comment I concluded that array and binding patterns were inconsistent and that it would be nice ot unify their behaviors. However, in the process of working on this, I discovered #4598 and the description of this PR indicates that they were not even meant to behave identically. This was in 2015 though, perhaps some adjustments could be made today.

Either way, to fix the reported problem we can:

make those implicit anys optional
pad the initializer type based on the padded parameter type (I dont like this at all ;p)
bring back padding in checkObjectLiteral so the initializer's type would have those properties. This would essentially revert a part of Fix circularity errors in intra-binding-pattern references #59183 . Note that in this situation... the initializer's type here would be { a: any } (and it was that in 5.5!), despite not having the a property
adjust how the initializer is checked against the padded parameter type. I'm not sure how exactly this would work since it's just using a regular assignability check today, so this would have to be a more involved change.
