React over Angular - my take

I took some time to learn React JS in the last few months. I created my little version of todomvc like application, created the same application using React and using Angular. The code lives here:

react-prototype
angular-prototype

Here is what I found. Overall I liked React much more than Angular for the following reasons:

  1. My debugging experience was much better. Angular brings JS into HTML and React brought HTML into JS. At first I cringed a little at the thought of having HTML within JS. As I kept building the application though it was much easier to debug issues. 
    1. First things first -- there was only one file to look at. Nothing more. All my JS and HTML is within one single file. Unlike Angular JS where I had to look at a directive, an HTML and a controller.
    2. JSX caught a lot of errors at compile time. This gave me more confidence. With the angular app I found errors at run time AND after a few hours of that error introduced.
    3. Easier to refactor - The above reasons made it easier to refactor the code as well.
  2. Componentization came naturally. With this I mean creating web components that can be distributed and reused much more easily. Again - having a single file helped a lot. I will be writing more about componentization in later posts.
  3. React definitely had a very small learning curve, much smaller than angular. It was much easier to explain React than Angular to my friends who knew nothing about both.
  4. Aligns well to Page Object pattern that is popular in testing circles. Although this is not the best of the reasons - it is worth a mention.
  5. The idea behind React makes complete sense. The part that model is the state and HTML is the projection of state and that only part of HTML that has changed is the one that is modified.
So - would I use React on my next project? This is a difficult question to answer. I would certainly advocate for it. A lot depends on the organization / project though. If there are Angular / any other framework experts out there and things are done well - there is no need to rock the boat.

Fuzzy Avenger

My latest new project on Github is Fuzzy Avenger.
https://github.com/daveayan/fuzzy-avenger


Why was this created?

This project started off as a learning exercise. This weekend I wanted to learn Akka with Java. In the process I created this github project to capture my learnings. The folders one - five in here is where that learning was captured. As I did that I realized a simple utility can be created that can be used with any traditional java code - specially unit tests or just for curious minds. This utility will process a list, apply a long running function (like making service calls) to each element in the list, capture results, aggregate them and will return the results. The results will be returned in the order - one for each element in the input list. Thus, this utility was created.

Why would I use this?

I would recommend not to use this in production code, yet.
Use this utility in your unit tests to exercise parallel processing / concurrency. For curious minds - to try out some instrumentation on your services For learning To provide me some feedback, if this is interesting, helpful and what updates can be made

Everyday Math from McGraw Hill Education

These days I am working on the version 4 of the Everyday Math program with McGraw Hill Education. The marketing team here prepared this video about the product we are building these days. The product is Everyday Math 4 that is targeted to students and teachers for grades K-6 and this will be launching in June for the 2014-15 school years.
The video features the authors of the EM, product sponsors, UX designers and academic designers from the Chicago office and showcases the product we are building.

Technical Skills for BA's and QA's

What kind of technical skills do BA's and QA's need? Terry and I had a good discussion on this quite a few times in the last year. Her recent email to the group soliciting feedback and ideas sparked a really good email conversation. Here is my take on this topic.

I think the technical skills needed by BA's and QA's depend a lot on Intranet / Internet system as well. With an internet system used by users all over the country / world BA's and QA's would need more technical skills around what are the minimum system requirements. Do we support multiple browsers / devices, what are the compatibility criteria and options. What are the trends in browser usage? What new technologies are coming in marketplace that may need to be accounted for - example, new version of Android or ipad mini :) If there is a new version of TinyMCE editor available do we upgrade? What does it buy us? etc

In an intranet system we may have a much more predictable user base. The technology standards are governed by a company wide "standards board" of some kind. This takes away the need BA's and QA's to know some of these technical items. In an Internet system where the user base is sampled and the technology terrain keeps changing much faster BA's and QA's need more technical skills.
