This release comes just a few months after the v3 release due to the much faster than expected turnaround on optional chaining by ESTree. Read on for more details!

AST 변화

공식 ESTree 옵션 링크 구문 지원(#2204)

When TS 3.7 released with optional chaining in November 2019, the feature was still a Stage-3 TC39 spec. This meant that ESTree[1] did not yet have an official AST representation defined, as they only officially support Stage-4 specs.

This meant that we either had to block on TS 3.7 support, unofficially support optional chaining, or find an interim representation to use. As we had no clear timeframe around which both optional chaining would move to Stage-4, and when the ESTree AST for it would be defined, we decided the first two options were sub-optimal, and instead chose to the existing babel-eslint AST representation. This representation has been in the ecosystem for a while and was supported by a variety of plugins.

Recently, ESTree agreed upon and merged an AST for optional chaining, which is vastly different to babel-eslint's representation. ESLint and their parser espree have already implemented and released support for this new AST as of ESLint v7.5.0.

In order to correct course to match the future of the ecosystem, we've update our AST to match the new, official representation.

This means a few things right now:

1. The ESLint core rules will have complete support for optional chaining, without need for extension rules :tada:
2. Users might have to wait for plugins outside this project to update their logic to support this new AST.

Going forward, we're trying to be a bit more conservative with our choice of AST representation to help prevent this migration pain, at the cost of not being able to write lint rules for new features.

[1] ESTree is the AST representation used in the ESLint ecosystem (amongst other things). It's collectively governed by a number of projects. https://github.com/estree/estree/

TS에서 지원하지 않음(#2375)의 데코더의 노드에서 데코더 제거

이전에 저희 해석기는 decorators를 해석하여 FunctionDeclarations, EnumDeclarations, InterfaceDeclarations의AST에 포함시켰습니다. 이것은 처음에 TypeScript 해석기가 여러 가지 이유로 문법적으로 유효하다고 생각했기 때문입니다. (TS 해석기가 허용하는 범위 내에서 매우 허용됩니다.)

변화를 타파하다

• • Removed decorators property from several Nodes that could never semantically have them (FunctionDeclaration, TSEnumDeclaration, and TSInterfaceDeclaration)

• Removed AST_NODE_TYPES.Import. This is a minor breaking change as the node type that used this was removed ages ago.

• eslint-plugin: Default rule options is a breaking change.
