Redux es un almacenador de estados

con redux nuestra aplicación puede trabajar con estados en un solo arbol de datos. Redux trabaja con unos cuantos métodos pero efectivos los cuales son

createStore
dispatch
getState
subscribe

un ejemplo básico:

task:

const fs = require('fs');
const param = process.env.page;
const webpackFile = './webpack.config.js';

const msgErr = (msg)=>{
	console.log(msg);
	process.exit();
}

Test promise

describe('unittest', () => {
    test('the data is peanut butter', () => {
        function fetchData(){
            return new Promise((resolve,reject)=>{
                resolve('peanut butter');
            });
        }
 expect.assertions(1);

bash git pull each dir

Execute command:

git_current_branch () {
  #https://stackoverflow.com/a/35298459
  echo $(git branch | grep '^*' | sed 's/* //' )
}
