React Native + Redux

-

I am creating an application with React native + Redux and I am new to Redux so I already know that in React native all Apis are converted into Java or Objective-C but what about Redux code, is it converting too into Java or objective-c ?

I recommend you to read an article about React Native architecture or even better - watch Tadeu Zagallo talk about how it works: https://www.youtube.com/watch?v=Ah2qNbI40vE

Simply said - most of the APIs are shimmed and backed by native implementation (e.g. fetch, AsyncStorage), though your application logic is running inside a Javascript VM (that also includes Redux, action creators, reducers etc).

So answering your question more specifically, your application logic is a Javascript code running inside a Javascript VM whereas APIs in most cases are native. Note that it's still possible to have more advanced logic computation done with Objective-C or Java as a part of a custom native module.

Meaning of `{}` for return expression

-
15 1 I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type? ...

Get current scroll position of ScrollView in React Native

-
Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native? So something like: <ScrollView horizontal={true} pagingEnabled={true} onScrollAnimationEnd={() => { // get this scrollview's current page or x/y scroll position }}> this.state.data.map(function(e, i) { <ImageCt key={i}></ImageCt> }) </ScrollView> Try. <ScrollView onScroll={this.handleScroll} /> And then: handleScroll: function(event: Object) { console.log(event.nativeEvent.contentOffset.y); }, Disclaimer: what follows is primarily the result of my own experimentation in React Native 0.50. The ScrollView documentation is currently missing a lot of the information covered below; for instance onScrollEndDrag is completely undocumented. Since everything here relies upon undocumented behaviour, I can unfortunately make no promises that this information will remain correct a ...
