Already, I’m Xamarin Developer. In my case as such, I wanted learn the React.js and React Native. I will be able to write React Native when I learn React.js.
I started to work immediately. Firstly, I did required installations. And I created first application with name of grapefruit.
I used flexbox-grid, webpack, babel, axios(for api requests) and etc. packages. I’m showing last posts from the Medium through rss to json api. I’m calling rss feed from Medium and converting json with rss to json. And I made all things without known very well React.js.
You shouldn’t think, “Which I should learn the language, Which is best etc.”. Just do it. Believe me, you can. I made without known very well that framework.
To tell the truth, new things always well. I advise you.
