* Allow special property assignments in TS
But only for functions and constant variable declarations initialised with
functions.
This specifically excludes class declarations and class expressions,
which differs from Javascript. That's because Typescript supports
`static` properties, which are equivalent to property assignments to a
class.
* Improve contextual typing predicate
Don't think it's right yet, but probably closer?
* More fixes.
The code is still fantastically ugly, but everything works the way it
should.
Also update baselines, even where it is ill-advised.
* Cleanup
* Remove extra whitespace
* Some kind of fix to isAnyDeclarationName
It's not done yet.
Specifically, in TS:
Special property assignments are supposed to be declaration sites (but not all
top-level assignments), and I think I
got them to be. (But not sure).
In JS:
Special property assignments are supposed to be declaration sites (but not all
top-level assignments), and I'm pretty sure ALL top-level assignments
have been declaration sites for some time. This is incorrect, and
probably means the predicate needs to be the same for both dialects.
* Add fourslash and improve isAnyDeclarationName
Now JS behaves the same as TS.
* Cleanup from PR comments
* goToTypeDefinition: Go to function return type
* Add more tests
* If a function returns 'void' or some other type with no definition, just return the function definition.
* Remove index signatures from js literals, use an object flag to indicate errors should be ignored instead
* Add focused test on the keyof problem
* Fix fourslash test
* Reenable errors with noImplicitAny flag
* Also disable excess property checks outside of noImplicitAny mode for js literals
* Edit and move comments
* importFixes: When one file redirects to another, consider both for global import specifiers
* Add test for #26044
* Avoid a symlinked package globally importing itself (fixes another case of #26044)
* Compare to node_modules with getCanonicalFileName
* Fix inferFromUsage on index signatures
1. Check the argumentExpression to determine the index signature type.
Previously, the code mistakenly checked the type of the element access
itself, which never returned a good type.
2. If inference for the index signature type fails, substitute anyType.
Previously, the code would create a bad index signature with an
undefined type.
3. Add tests. Previously, there were no tests.
* Fixing (1) means that number index signatures are now created.
Previously, only string index signatures would be created.
* Fixing (2) means that index signatures will be inferred from single
usage like `return a[0]`. Previously, the refactoring would fail,
perhaps because of a check when stringifying the index signature (I
haven't tracked down why.)
* Update fourslash test with improved inference
