Is there a way to enable support of optional chaining operators in WebStorm

Question

I work on a project where we use optional chaining operator (aka Elvis operator):

const baz = new obj?.foo?.bar?.baz()

Is it a way to make WebStorm understand it?

PS It's a part of stage-1 proposals: https://github.com/tc39/proposal-optional-chaining

Answer 1

Finally typescript version 3.7 supports optional chaining. For webstorm to support it you need to update it to the latest version. It would work as expected.

Typescript - https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html

Webstorm Release notes - https://blog.jetbrains.com/webstorm/2019/10/webstorm-2019-2-4/

Here is an issue about this https://youtrack.jetbrains.com/issue/WEB-27592 . Seems like it's resolved so we can wait for the feature in next build.
