What are the best language for building native web apps. mean or react native or any other ?

Ionic1... every other way is waste of time and resources. And yes, ionic2/3 are fucked up, because of some idiot who thought, that typescript way will be better.
Also, flutter.io looks promising because of dart language.

For mobile apps, best languages:
Swift
Java
Kotlin

That hybrid shit can go to hell

HTML

I thought about ionic.. I don't think it will be useful for startups and testers. I have to pay for a large scale use of my app. When I can build my app in native java and release it in playstore for the cost of play store licence.

@gitpush but am guessing hybrid is becoming the new future coz all the major tech companies are web apps now.

@sathya741 it's not becoming standard. And to be honest, I don't think it ever will. Web apps are total shit, their performance is trash, they can't use all features of your phone. If you want to release on both OSs, just use flutter.io. In the end you will get 2 native apps with 1 codebase, adding system specific features in Java/Swift.

How can an app be native and a web app?

@sathya741 and what does a web app has to change for the mobile platform? What I would understand is companies following hybrid to prevent maintaining two code bases for mobile.

But everything is at a cost, one has to chose what is best for their current situation, for me I'd rather write the code twice than writing it once and use hybrid solutions

I have mistakenly told web apps instead of hybrid apps. I think hybrids are quite useful. Let's say am a startup company with low budget, I can simply create a hybrird app and publish it in many platforms. I can use pretty much everything I need in a phone. But that scenario may change because of app store new guidelines.
