Thanks for your thoughts, Paul. I disagree; there are millions of Ionic developers now and I bet the numbers are similar with React Native. It’s definitely making more than a dent. :)
That’s fair about RN — I included it because it’s what I would label an alternative way of creating mobile apps — hence the mention. At the end of the day, it’s an exciting time to be a web developer, with many options available that you can look into. If it’s not for you, that’s perfectly OK.
