E0273: TypeScript namespaces are not allowed in JavaScript
TypeScript supports namespaces to describe objects. JavaScript does not support
this syntax. It is a syntax error to use TypeScript's namespace
keyword to
create a namespace in JavaScript:
namespace goog {
export class Chart {
// ...
}
}
To fix this error, create a variable with an object instead:
const goog = {};
goog.Chart = class Chart {
// ...
};
Introduced in quick-lint-js version 2.8.0.
