  • Fix a crash when parsing inline TypeScript decorators (#2991)

    Previously esbuild's TypeScript parser crashed when parsing TypeScript decorators if the definition of the decorator was inlined into the decorator itself:

    @(function sealed(constructor: Function) {
  Object.seal(constructor);
  Object.seal(constructor.prototype);
})
class Foo {}

    This crash was not noticed earlier because this edge case did not have test coverage. The crash is fixed in this release.
