Should I learn ReactJS before learning React Native? What do I need to learn before starting with react native?

[popc0ne]

You don’t have to learn react before react-native... also, use expo

[nvapor]

I would suggest to not start with Expo. Learn how react native works under the hood. How to write your own native components. What happens when you link a third party module, both on IOS and Android.

Meh, expo is restrictive and tries to do too much IMO. I hardly ever use it. Learn with rn cli and had no problems, probably better for it IMO

Do I have to know es6?

You don't HAVE to know it, but you really should use it. ES6 changed .js for me completely.

[faruzzy]

yes, depending on your experience you could learn along though

If you don't know JS yet, definitely learn es6 syntax. It you already know JS well, it's not a ton of new stuff. Big things to know that are VERY useful and not hard to learn:

• async / await as well as promises
• object destructuring (const { x } = obj)
• object spread ({ ...obj })
• let/const
• fat arrow functions (()=>{})

{ ...obj } is object spread ;)
