You can only do default exports from CommonJS modules. import packageMain from ‘commonjs-package’; // Works import { method } from ‘commonjs-package’; // Errors This means that all commonjs exports will live on the packageMain object, and you need to dot in to the packageMain object to pickup … Read more
for (var [key, value] of myMap) { console.log(key + ” = ” + value); } is like for (let pair of myMap) { var [key, value] = pair; console.log(key + ” = ” + value); } So it’s not myMap that has to be an array for the destructuring to work; rather, each of its … Read more

One possible solution, as you already mentioned, is to use channels. Here is an example that should work in your case: import { channel } from ‘redux-saga’ import { put, take } from ‘redux-saga/effects’ const downloadFileChannel = channel() export function* loadFile(id) { … const download = RNFS.downloadFile({ … // push `S_PROGRESS` action into channel on … Read more
Sadly as you’ve figured out there are no native intersection or union operations. It’s not terribly complex to find the intersection though: let a = new Set([1,2,3]) let b = new Set([1,2,4]) let intersect = new Set([…a].filter(i => b.has(i))); console.log(…intersect)
It is better to follow official documentation and to use state property. There are two good reasons for that: You want to keep all things that have effect on a component render result in your state/props/context. React-Native Animated library has its own optimizationzs that allows to avoid setState calls and re-rendering on change of Animated … Read more
