Angular 8 language enum

[Venugopal Ibharampur]

I am trying to integrate google transliterate in Angular 8 application. But Since I am beginner in Angular. I am bit confused over using languages as enum.

Can someone please help me in writing languages enum in angular 8 or mention working stackblitz where I can take a reference.

I was referring following link to to POC for my angular application.

Any help on this would be great.

Thanks,

Venu
