Playing with Promise syntax

promise-test.js

require('es6-shim');

function doSomething() {
  console.log('doSomething');
  return Promise.resolve();
}

function doMore() {
  console.log('doMore');
  return Promise.reject(Error('failed'));
}

function recover1() {
  console.log('recover1');
  return Promise.reject(Error('failed'));
}

function recover2() {
  console.log('recover2');
  return Promise.reject(Error('failed'));
}

doSomething()
.then(doMore)
.catch(function catch1(err) {
  console.log('catch1');
  recover1()
  throw new Error('error in the middle of error handling')
  recover2()
})
.catch(function catch2(err) {
  console.log('catch2');
});

Output:

doSomething
doMore
catch1
recover1
catch2
