@FelippeRegazio Pra quem ficou curioso sobre o "inner", usando o dá pra ver que é um "LabeledStatement" e não muda em nada a criação do "BlockStatement" que faz qualquer "VariableDeclaration" ser escopado pro bloco. Mais sobre labels:

TLDR of how it works. tokenize():.Turns `boop a = 3` to [{token: 'boop', type: 'variableDeclarator'}, {token: 'a', type: 'identifier'}, . ]. parse():.Turns token array to AST {type: 'VariableDeclaration', id: {type: 'Identifier', name: 'a'}, init: {type: 'Number', value: 3}}
I made a programming language this weekend 🥳. Here's "blep"! define variables with `boop` and print with `bark`. boop a = 3;.boop b = 5;.bark(a + b). npm install -g blep.

JavaScriptのAST操作で VariableAssignment 弾いて VariableDeclaration だけ通せば一応デフォルトでコンストになるな.

Okay, yes, technically you can just prefix it with a `//` or surround it with `/* */`. You can even add quotation marks to turn it into a string. But not what I had in mind. The new rule is you have to leave this as a valid VariableDeclaration.

とりあえず自分が上げたissue, importTracker.tsのgetExportNode関数でSyntaxKind.VariableDeclarationかどうかの判定方法がマズいというところまではわかった.

今まであんまり区別してなかったけど、var x = 3 って VariableDeclarationの init 付き変数宣言のStatementだけど、x = 3 は ExpressionStatementのAssignmentExpressionなのか。そりゃそうか。.

コンポーネントであることを明示するためにReact.FCを使いたくてそのためにVariableDeclaration+FunctionExpressionで書くというのも本末転倒で、ReactNode型を返すように明示すればよいし、なんならReactNode型を満たすものでなければ単に実行時エラーなのだから区別したがる意味がない.

type-explorer、初期実装としてとりあえずTypeAliasDeclarationを対象にしてts.Nodeを走査して型情報を引っ張ってきてた���ど、VariableDeclarationから型情報得ようとするとts.Nodeの実体が存在しないため無事死亡.

むー、esprimaは、共通のNodeみたいな型が無くて、ProgramとかVariableDeclarationとかみたいな型がそれぞれ別途あるのね….

await t; ってコードがどう AST になるんだろうと思って調べてみたら VariableDeclaration になってて笑った。 contextual keyword の実装めっちゃ大変そう.
