* Fix 'arguments' check in class field initializer or static initialization block
* return errorType
* Merge branch 'master' of https://github.com/exoticknight/TypeScript
* use isInPropertyInitializer
fix Diagnostics message
* Don't attach declarations to symbols in mapped types with 'as XXX' clauses
* Add test (and tweak comment)
Co-authored-by: Eli Barzilay <eli@barzilay.org>
* Add test case for 'useUnknownInCatchVariables'.
* Add new 'useUnknownInCatchVariables' flag.
* Accepted baselines.
* Add test for catch variable explicitly typed as 'any'.
* Accepted baselines.
* Move option under 'strict'.
* Accepted baselines.
* 'useUnknownInCatchVariables' is strict in command line help.
* Ensure static index signatures have an errorNode available
* Lookup static index signature declarations in the right symbol table, stop checking prototype props
* support QualifiedName when narrowing inside loops
* add test
* narrow more qualified names
* handle `undefined` of `getFlowCacheKey `
* update comments in test
* Private identifiers use standard identifer scanning
Previously they used an old copy of the identifier scanning code that
didn't handle extended unicode yet.
* gotta fix that const lint
* Cache accessibe symbol chains, type parameter name generation
* Move signature declaration helper length approximation to start of function
* Add node result caching internal to `typeToTypeNodeHelper`
* Suggestion from PR
The [String.raw spec](https://tc39.es/ecma262/#sec-string.raw) uses just
the `raw` property of its first argument, which is a useful way of using
it in user-defined tag functions to do the work of interleaving strings
and values as well as converting the values to strings.
Fixes#43609.
* Allow filterType to consider union constraints of non-union types when determining never-ness
* Move impl to callback
* Baseline change in narrowing behavior into test, fix post-LKG build
* Test where relative import isnt ideal in the declaration emit
* use project relative preference for declaration emit
Fixes#39117
* Fix incorrect path matching when calculating module specifier
* Use correct baseUrl for the module specifier
This diff extends the types checked by
discriminateContextualTypeByObjectMembers and
discriminateContextualTypeByJSXAttributes to also include any optional
components in the type union.
fixes#41759 although it doesn't address the better error reporting for
their last repro, which I'm not sure how to address.
* Use faster, stricter prop type comparison when merging props in union prop creation
* Be better at determining this usage in methods, accept baselines
* Small style change
* Consider identical instances of the same symbol equivalent when creating union and intersection properties
* Also copy over mapper and type (if available) on cloned symbols
* Editorial feedback
* Ignore object types in intersections with primitive types
* Add regression test
* Also handle instantiable types constrained to object types
* Add another test
* Add ignoreObjects optional parameter to getTypeFacts
* If target:esnext,then useDefineForClassFields: true will now be the default.
* Added error if a private identifier is used in a static a initializer if target:ESNext and useDefineForClassFields:false.
* Added test for new useDefineForClassFields default and error message.
* Fixed tests after changing the default of useDefineForClassFields to true for target esnext
* Fixed code review suggestions.
* Updated error message.
* Added missing static check for the containing property. Fixed other code review issues.
* Fix getRecursionIdentity, undo changes from #43435 (but keep tests)
* Remove test that takes excessively long to run
* Accept new baselines
* Fix formatting
* Add regression tests
* Reinstate test
