How to setup start position in Los angelis when coordinates is 34.0544779, -118.2443409?!

Try by inverting lat and long ? Did you try with [-118, 34] ?
@VentsislavDinev this code snippet is for mapbox-gl-js this is the react-native repo you will want to open up issues here https://github.com/mapbox/mapbox-gl-js.
I agree that your coordinates look like they are in [lat, lng] order and they need to be in [lng, lat] order.
LMAO I thought I was doing something wrong on my end until I saw this error message on my Chrome debug window.
