* fix: convertFunctionToEs6Class cannot recognize `x.prototype = {}` pattern
* test: add test for convert fn to es6
* chore: add more tests
* chore: move tests around
* chore: make code more clear
* Adds support for looking up past Blocks in expando objects
* Adds JS tests to validate the JS parsing also works
* Get the top level block expando tests green
* Prefer a likely literal over anonymous type in --noImplicitAny codefixes
Before trying to make an anonymous type for a type's usage, we'll first check if there is exactly one builtin primitive the usage is assignable to, and use it if so. Right now that's only `number` and `string` because `boolean` has no distinguishable members.
A couple of implementation details:
* `tryInsertTypeAnnotation` needed to know to insert a type _after_ a node's `exclamationToken` if it exists
* This code area was written before `??` 😉
* Used unknown/any instead of void when applicable
* Fix little whitespace change in tests/cases/fourslash/codeFixInferFromUsagePropertyAccessJS.ts
* Undid some now-unnecessary unknown additions
* Took advice on restricting void to just call expressions
initialiser. But this is only correct when the initialiser is for a
parameter. For example:
```ts
declare let x: { s: string } | undefined;
const { s } = x;
```
This PR removes undefined from the type of a binding pattern only when
the binding pattern's parent is a parameter. This fixes the regression
from 3.8. However, it's still not the ideal fix; we should be able to
use control flow to solve this problem. Consider:
```ts
const { s }: { s: string } | undefined = { s: 'hi' }
declare function f({ s }: { s: string } | undefined = { s: 'hi' }): void
```
Neither line should have an error, but the first does in 3.8 and after
this change.
* Remove superCallShouldBeFirst error
It seems redundant since TS gives an error on any use of `this` before
super, and non-`this` uses before `super` should be fine.
Fixes#37371
* Revert "Remove superCallShouldBeFirst error"
This reverts commit 3c09153c8ad00d73d60e7000a0e6263a6028615a.
* error except for target:"esnext" && useDefineForClassFields
* Fix use-before-def with methods on esnext+useDefineForClassFields
It was incorrectly flagging methods as used before their definition, but
this is allowed under any emit.
* Add instance function test case
* Propagate nonInferrableType in &&, || and ?? operators
* Add regression test
* Simpler solution: getTypeFacts(neverType) should return TypeFacts.None
* Fix prepending unused TypeScript variables with underscore doesn't rename JSDoc @param.
Fix test for quick fix "Prefix all unused declarations with '_' where possible".
Fixes#33021.
* Replace FindAllReferences.Core.eachSymbolReferenceInFile function call to more ligher call of getJSDocParameterTags when searching for a parameter in jsdoc.
* Remove redundant constant declaration.
* Add test for prefix single unused parameter in jsdoc.
* add two tests: Refactor: Remove braces from arrow function
* refactor: simplify test and add another test
* fix: copyTrailingAsLeadingComments in addOrRemoveBracesToArrowFunction
* test: add additional test
* fix: clean up changes
* fix: add check for newEdit
* fix: add function for semi colon modifier
* feat: grab all comments during refactor
* refactor: update addOrRemoveBraces logic
* fix: remove duplicate function call
* Update src/services/refactors/addOrRemoveBracesToArrowFunction.ts
* remove blank line
remove blank line
