Chaining promises with just a single error handler

chaining.js

var Promise = require('promise');

var limit = 3;

var doAsync = function(nbr) {
    var promise = new Promise(function (resolve, reject) {
        setTimeout(function() {
            if (nbr <= limit) {
                // increment the given value by 1
                resolve(nbr+1);
            }
            else {
                // reject the promise if nbr is over the limit
                reject('Number is over limit: ' + nbr);
            }
        }, 10);
    });
    return promise;
};

var handleSuccess = function(result) {
    console.log('Success: ' + result);
};

var handleError = function(error) {
    console.log('Error: ' + error);
};

// each call to doAsync increments the value by 1
// then is passed to the next step in the chain
doAsync(0).then(doAsync).
    then(doAsync).
    then(doAsync).
    then(doAsync).
    then(doAsync).
    then(doAsync).
    then(doAsync).
    then(handleSuccess, handleError);
