Hey there! I am no expert, but i started as a junior developer (1. July) and work with React js.
As i was making some investigation when confronted with the topic, my research showed: React is ideal for building dynamic, high performing, responsive UI for web interfaces, while React Native is meant to give your mobile apps a truly native feel.

As React.JS is the heart of React Native, i wooould suggest you start with that, then when you want to build apps that are optimzed for mobile devices, have a look at native.

As mentioned, I am a beginner but that's what i think. :)

Have a great day

Hey there :)
This is my first activity ever here :D
You have mentioned about mobile development, but why not to connect both world and give people better experience?

You can write logic for both: web and mobile and connect it to separate view for mobile and web.
Check this article and repository mentioned there:

codeburst.io/reusing-code-between-...

If you will start experimenting with that and will get any conclusion if it is fine way, I would be happy to get feedback :)

Hello Lavinia, I believe you should focus first on a platform. Anyway you can reuse a lot of the code on both platforms.

Good studies!

You should look into Progressive Web Apps (PWA). They'll give you the possibility to have all three (mobile webpage, desktop webpage, mobile app) in one. In fact, dev.to is a PWA. You can add it to your homescreen, so that when you open it like that it will look and feel like a native app.

It also has the advantage of not relying on app stores. People can just "install" them from the browser.

Furthermore, to answer your question, I would learn Reactjs. The techniques are largely the same, so if you know one of them by heart, you'll be able to work with the other one as well. The reason I'm suggesting ReactJS is because it's easier to set up the environment IMO.

If you're asking that question, the answer is react. You can't do react native without react. Just do the one. A diversified focus will make it too difficult to learn either. Also, React Native is slowly getting replaced by other things - including ways to just use plain react to make apps instead. Like Capacitor

hi, You can start with anything you like, i started with react native by directly working on live project from scratch, it help me understand working of react and after seeing some tutorial of reactjs, i am able to work on same time

Depends on what you want to build.

I think React is a lot easier to get into than React Native because of the Toolkit on top of React Native, Simulators and differences between Native Components and simple elements like div in normal React.

Folks are rightly mentioning PWA and building react apps that render on mobile and tablet and desktop. Give that a go. If you look at react native then they go native. The really good sample apps have to recode between ios and android; yet they can go deeper in each. Fiddling around with why a line is duplicated in android but not ios is okay to solve if you are being paid to solve it. If you are tying to learn to build general things then starting with react at PWA is going to cover more ground.

Consider flutter? flutter.dev/

It's on top of my list of things I would like to try.

The basic principles of React apply to both. With react-js you can target browsers and mobile via Ionic. Also try to learn a little bit of native development if you want to go deep into mobile apps. It helps you to understand what's going on behind the scenes of react-native and sometimes you just need to dig into native code when something doesn't work with react.

React or React-native both require a good knowledge of es6 and javascript. I think the difference is that react-native has it's own component like View, Text, instead of divs and p.
Learning any one of this will benefit both of them in my opinion. :)
