This is a mix of changes, most importantly:
- Always print parens when mixing nullish coalescing and another logical
- Fixes assignment in the callee of an optional chain, which now blocks #11248
Also, cleans up a bit of code, and removes an unnecessary parens around `class A extends new B {}`
* Added precedence for nullish-coalescing-operator
* Made precedence equal to logical OR
* Renamed the folders made for testing
* Fixed the output test file of nullish-coalescing op
* [parser] Add support for TS declare modifier on fields (#10484)
* [parser] Add support for TS declare modifier on fields
* Use Object.create(null)
* Comment
* Add support for TS declare types to types and generator (#10544)
* Transform TypeScript "declare" fields (#10546)
* Transform TypeScript "declare" fields
* Remove multiple spaces
* declareFields -> allowDeclareFields
* Update after rebase
* Flow enums parsing
* Parse exporting enums
* Enums parsing remove lookahead, other improvements
* Enums: add EnumBody and EnumMember aliases, change boolean members to use BooleaLiteral value
* Fix enum member init flow type, now that boolean members have a BooleanLiteral value
* Flow enums: use contextual utils, change members length checks to use logic operators, remove reserved word logic modification
* Flow enums: remove unnecessary code in generator, fix error message
* Add windows to travis
* Update
* Do not use sh file on windows
* Fix whitespace
* Unify command
* ./ doesn't work on windows
* Remove all ./ usages
* Run windows test before others
* fix: normalize filename when generating sources
sources should be URL.
* fix: replace normalized path to cwd
* chore: add nodePlatform task options
* fix: normalize preset-env filename output
* chore: replace normalized path to CWD on win32 platform
* limit transform-react-source to run on linux and darwin
* test: escapeRegExp on testcases
* test: add test for babel --filename on windows
* test: double babel-node/cli test timeout
* chore: workaround windows build does not stop
* chore: remove redundant condition
* refactor: rename `nodePlatform` to `os`
* feat: v8intrinsic syntax plugin
Implement V8 Intrinsic Syntax Extension. Here we check the execution branch inside the parseSubscript to make sure the V8IntrinsicIdentifier is immediately followed by a call expression.
* feat: disable combining placeholders and v8intrisic
per https://github.com/babel/babel/issues/10104#issuecomment-506950969
* test: add more error cases
* refactor: parse v8 intrinsic in parseExprAtom
This approach is identical to V8’s implementation. Move the test cases as the behaviour changes.
* fix: plugin-name typo
* test: add yield-expression test case
* feat: require startsExpr on modulo for v8intrinsic
* perf: skip eof and braceR check as they must return false
* Print V8IntrinsicIdentifier
* feat: add v8intrinsic to parser typings
* Add generated type helpers
* fix: incorrect type definition
* fix: allow V8IntrinsicIdentifier to be callee
* ♻️ added condition to check for left and right of nullish coalescing operator and if any is a logical expression without a paren then throw an error
* 🐛 bugs fixed and test cases updated for babel parser
* ♻️ code comments added
* 🐛 spell error rectified
* ♻️ failing test updated
* 🐛 push tests after make build
* Skip nullish-coalescing flow precedence tests
They're now incorrect
* ♻️ error message updated, binop priority of other logical operators +1 from ?? and
* ♻️ increaed the binOp for in and instanceOf, added logic to print the brackets in an ?? && || expression, test cases added
* 🐛 failing test fixed and comments updated
* ♻️ new lines added between tests
* ♻️ basic tests for checking the binOp of instanceOf, in and relational operators to be equal added
* ♻️ new lines added in between tests
* Add ";" token to the end of TS construct signature declaration
* Add ";" token to the end of TS call signature declaration. Update construct signature test fixtures
* add partial application syntax and some tests
* remove unnecessary error message and hasPartial function from parseNewArguments
* add types for PartialExpression
* Update the tests
* rename PartialExpression to Partial
* move Partial from expressions to types and rename to ArgumentPlaceholder
* add tests for ArgumentPlaceholder in babel-generator
* rename Partial to ArgumentPlaceholder
* update the tests
* remove alias from the type and undo changes in generated folder
* adds a nice error message
* better definition for the type
* auto-generated files
* update the conditional for allowPlaceholder message and tests
* update CallExpression definition to accept ArgumentPlaceholder
* change description
* clean up
* indent ArgumentPlaceholder entry and revert unwanted changes
When I was reading the code, I see `parent` is not used in `_getComments` function.
so it make me confused why we delivery the `parent` in those functions.
If I'm wrong, please correct me.
* Fix private property parsing in Flow
* Flow tests updated
* Fix type error
* Appropriate name was given to test folder
* Fix
* Empty
* Correct type annotation
* Add required changes in generator package
* Add required changes in flow-strip-types
* Add sourcemap examples for identifiers in code generator.
* Generate sourcemaps with exact mappings for identifiers, even if leading/trailing tokens also use that location.

@JamesHenry This changes the AST format. CC @DanielRosenwasser for review.
Supports parsing type arguments on tagged template calls.
Should wait on Microsoft/TypeScript#23430 to be merged so we're sure we have the final syntax.

See eb815be907 for more information about this feature.
The proto modifier indicates that a property declared using `x: T` syntax is actually present on the prototype object of the class, rather than an own property.
The proto and static modifiers are mutually exclusive, as class declarations don't simultaneously define the static prototype object, as they do the instance prototype.
This syntax is only supported on declared classes, not object types, interfaces, or runtime class declarations, and as such should only appear in library definitions.
