function parseEmptyStatement(): Statement { const node = <Statement>createNode(SyntaxKind.EmptyStatement); parseExpected(SyntaxKind.SemicolonToken); return finishNode(node); } 可以得出createNode函数是真正为我们创建节点的地方

With this option, a type modifier is added if "importsNotUsedAsValues": "error" or "verbatimModuleSyntax": true is specified in your tsconfig.json. Otherwise, if no import type is preferred, no type modifier is inserted. Gif If there is already an import statement with a type modifier, ...
Instead, TypeScript can now operate over the original syntax nodes directly, which is much cheaper and faster. Easier API Consumption from ECMAScript Modules Previously, if you were writing an ECMAScript module in Node.js, named imports were not available from the typescript package. Copy import...
If you haven’t yet heard of TypeScript, it’s a language based on JavaScript that adds static type-checking along with type syntax. Static type-checking lets us know about problems with our code before we try to run it by reporting errors if we do something questionable. This ranges from...
