For a web developer that wants to try mobile development, which is better, native (java-swift), or react native?

It was my first job, I went to the interview and the interviewee started looking at my github then he said you're hired you can start tomorrow. The next day I knew they had a web developer who worked there for a week and left because of college and they had projects to do so they just hired me.

I'm not even employed

Fucking youtube

Hello developers,
This is my first rant here, I'm a new developer from Egypt, 20yo.
I started learning web development last January and now i have a pretty solid establishment in development.
Till now I'm a MEAN stack - angular(still learning it)
Do i start to apply for jobs right now or do i should wait a few months till i get better, i already have some web applications that can be put into the portfolio.
