Array.isArray is deprecated now? [closed]

Question

I'm coding TypeScript on WebStorm IDE. The IDE tells that the method Array.isArray is deprecated (like in the image), and I doubt it. Also, I couldn't find information about it

let items: any[] = Array.isArray(jsonData.items) ? jsonData.items : [];

is Array.isArray really deprecated? Thanks

Answer 1

Array.isArray appears in the latest draft specification where it is not marked as deprecated.
