Optional chaining and Nullish coalescing don't work with Typescript

Ionic Framework Ionic Vue

Hello :slight_smile:

I am facing errors when i try to use ? or ?? operators with Ionic Vue (Typescript)
Examples:
user?.name
const value = test ?? ‘Default’

If i try it without lang=“ts” on script it works
Also those features works fine on Vue 3 project generated with vue cli.

Errors:
Module parse failed: Unexpected token
…
You may need an additional loader to handle the result of these loaders.

Best regards

Add samsung 12.0 to your .browserslistrc file and restart the build (i.e. rerun whatever command you used to start the local server).

e.g.:

//.browserslistrc

not dead
not ie 11
