* avoid circularity in getTypeOfVariableOrParameterOrProperty
Modify getTypeOfVariableOrParameterOrProperty to get the type of the
variable declaration before widening it. This essentially avoids some
circularities by (1) setting the type of the variable declaration to the
unwidened type (2) updating the type of the variable declaration to the
widened one.
You will still get a circular noImplicitAny in (1), for expressions that
actually are circular, but not in (2), for the containers of things that
are not themselves circular.
* Stop checking js init object literals via checkObjectLiteral
* checkBinaryExpression: new code for special assignments
* Chained lookup for js initializer type
* Check for JS-specific types only once
Also make sure to respect the type annotation if there is one.
* Accept API changes
Nearly everything in a merge of JS special assignments looks like a
valueDeclaration. This commit ensures that intermediate "module
declarations" are not used when a better valueDeclaration is available:
```js
// File1.js
var X = {}
X.Y.Z = class { }
// File2.js
X.Y = {}
```
In the above example, the `Y` in `X.Y.Z = class { }` was used as the
valueDeclaration for `Y` because it appeared before `X.Y = {}` in the
compilation.
This change exposed a bug in binding, #24703, that required a change in
typeFromPropertyAssignmentOutOfOrder. The test still fails for the
original reason it was created, and the new bug #24703 contains a repro.
Do this by not widening properties of an object literal that are
1. JS initialisers
2. and not an object literal
These properties have types that will never widen, so the compiler
shouldn't ask for the types earlier than it strictly needs to.
* Simplify parseJSDocIdentifierName
It now always creates a missing node. The one place that depended on it
returning undefined, parseJSDocTypeNameWithNamespace, now returns
undefined before calling parseJSDocIdentifierName.
* Remove assert
It is adequately proven at compile time.
* Use more nodelike paths for import types when possible
* move functionality from services into compiler, fix with propert file/directory conflict handling
* mark suspect cast
* If parsing a function type fails, parseTypeReference() to ensure something is returned
* Avoid tryParse
* Add missing semicolon
* Don't check for undefined, check for missing type
* Don't set parameters undefined, set to missingList and return false
* Update API baselines
* Code review
Fix the issue with createSemanticDiagnosticsBuilderProgram, createEmitAndSemanticDiagnosticsBuilderProgram and createAbstractBuilder not assignable to CreateProgram<T>
