I agree that browsing the code and discovering references is facilitated in Typescript, but a good Javascript IDE (for example WebStorm) can do these with acceptable accuracy too. Of course it is easier in TS, but I’ve seen Microsoft’s own IDE (VSC) sometimes fail to find the right reference due to the dynamic nature of the language.
