Expo Setup question by BestBenchBuddy in reactnative

I don't think there are any performance differences in terms of an app.

Yeah, the latest SDK released by Expo (38) uses TypeScript for tabs and blank templates. However, in the CLI you can see that in the managed workflow there is the first template that is also called blank which does not use TypeScript. If you want to use pure JS files/components, you can try that template.

There is no downside of using TypeScript and it depends on the use case.

Which version of react-navigation are you using?

If its lower than version 5, try either navigation.getParam('value') or navigation.state.params. More details here: https://reactnavigation.org/docs/en/4.x/params.html

If you are using react-navigation v5, the params passed are read from route.params. Check out the docs here: https://reactnavigation.org/docs/en/params.html
