Element implicitly has an 'any' type because type 'Window' has no index signature?

Question

I\'m trying to create a Factory class in Typescript, but running into the following error:

src/ts/classes/Factory.ts(8,10): error TS7017: Element impl

Answer 1

Another way to index on window, without having to add a declaration, is to cast it to type any:

return (window as any)[className];
