* use symbol to expression. TODO: filter existing, replace import nodes
* WIP
* WIP

* fix element access expression case
* refactor dealing with existing values into a tracker
* fix merge errors
* cleanup and more tests

* address small CR comments
* fix completion entry details; add test case
* fix lint errors

* Fixed an issue with `in` not being able to be used on narrowed down expression of a generic nullable type
* Add another test case from a new issue
* Move the fix to `hasEmptyObjectIntersection`
* Refactor `Extensions`, fix lookup priorities
* Update baselines
* Clean up
* Temporarily apply same fix to `node` for testing
* Revert ancestor node_modules lookups back to two passes
* Revert "Temporarily apply same fix to `node` for testing"
This reverts commit 4014f3005a.
* Update baselines
* Add new test for node_modules searching behavior
* Update new baseline
* Add known keys of the mapped type constraint to its members
* Avoid second pass of adding known members by instead passing `noReductions` to `mapType`
This adds a "small" d.ts bundler script. This script is very basic,
using Node printing to produce its output. Generally speaking, this is
inadvisable as it completely disregards name shadowing, globals, etc.
However, in our case, we don't care about the globals, and we can opt to
restructure our codebase in order to avoid conflict, which we largely
had to do anyway when we were namespaces and everything was in scope.
* Fixed a regression with discriminating unions based on a union property against `undefined` with `strictNullChecks: false`
* Add additional test case from the issue comment
* Fix enum classification and evaluation
* References in literal enums must be to other enum members
* Accept new baselines
* Unify enum types + template literal constant expressions
* Accept new baselines
* Fix fourslash tests
* Fix new compiler errors
* Fix lint error
* Accept new API baselines
* Fix test
* Better error message + consistently check enum initializers
* Accept new baselines
* fix(51301): keep the line break after removing the unused identifier
* preserve line breaks in import specifiers
* preserve line breaks in parameters and destructuring elements
* remove preserveLineBreak option
* fix(50551): handle destructuring variables used before assignment
* skip the error in binding elements that refer to the same destructuring
* fix binding element type
* added test case to try to retrieve duplicate refactor as in #50416. 'verify.refactorAvailable' correctly retrieves nonduplicate refactors...
* optional arguments in refactorAvailable return `true` even if there is no single refactor that satisfies both
* it still passes :C
* Delete fixExtractToInnerFunctionDuplicaton.ts
* deleted extra test code
* fix 'verify.refactorAvailable' so that tests correctly check for multiple arguments
* fixes#50416
* refactor
* feat(37440): add QF to handle missing exports
* change diagnostic message
* add type modifier only if isolatedModules is set or if the export declaration already uses type modifiers
* Check nested weak types in intersections on target side of relation
* Add regression tests
* Move logic from isRelatedTo to structuredTypeRelatedTo
* Fix lint error
* Add additional test
