* Refactor trailing comment adjustment
Following up from https://github.com/babel/babel/pull/10369
- Unify the logic for adjusting trailing comments into a separate
function
- Use it for all three cases, which fixes a bug for ObjectExpressions
and CallExpressions
- Update tests to check for the fixed bug
* Fix tests
- Only modify trailingComments if necessary
- Update snapshots of a couple of affected tests
* Drop the underscore in adjustCommentsAfterTrailingComma_
* Handle ArrayPattern
* Handle ObjectPattern
* Handle import and export declarations
These have to be handled a bit differently, because the node is visited after the and before the declaration. So we intercept when we are going from the last specifier to the source node.
* Remove unnecessary check
* Disallow escape sequences in async
* Disallow escape sequences in get, set and async in class
* invalid escape tests
* Update whitelist
* tests for async in parens
* Add test for invalid newline between params and arrow
* Move canInsertSemilcolon() into shouldPArseAsyncArrow
* Introduce scope tracking
* Fix tests
* Add new tests
* Remove constructor-super check from transform as it is now in parser
* Correctly handle class properties and class scope
* Fix duplicate name check
* Convert scope identifier storage to array
* Enter a new scope in typescript module blocks
* Add test for duplicate declaration
* Rename error for duplicate exports
* Treat class declarations as lexical declaration
* Update whitelist
* Add tests
* Fix scope tracking for function declarations
* Migrate try-catch duplicate error
* Fix test
* More tests
* One more test
* Make scope a separate class and fix review comments
* Do not allow new.target in top scope arrow function
* Correctly enter new scope for declare module and treat type aliases as lexical declarations
* Tests for typescript scope tracking to not mark type aliases as duplicate
* Fix flow scope tracking
* Remove ident from test names as redundant
* Add test case for var and function
* Improve error messages
* Improve literal regex
The extra field parenthesizedArgument was never set to true. It was
always set to false and the code that read this was incorrectly
checking if extra was present.
