WebStorm encountering TypeScript error with "nullish coalescing operator"

I am currently facing a problem while using WebStorm with TypeScript v3.7.5. In this particular version, TS introduced the `??` operator. I have implemented it in my project but it seems like WebStorm is not able to understand it and displays an `expression expected` error. Surprisingly, when I run the `tsc` command, no errors are shown.

When I open the code in VSCode, there are no errors visible, so I believe the issue does not originate from my TypeScript configuration.

Is there anyone who knows the reason behind this behavior and how to resolve it?

Answer №1

Which edition of WebStorm are you currently utilizing? The feature Nullish Coalescing has been supported since version 2019.3, for more information please refer to WEB-41494
