As a professional software developer I have had the luxury of being able to work on successful professional projects in AngularJS, React, and now the modern Angular. To me it's so funny how similar the two frameworks are in terms of the problem they are trying to solve and even the way they do it.

I've recently been building web applications with front-end frameworks like React, Reagent, and Angular 2. I was recently working on an Angualr 2 project and thought, "man, this sure seems like a ton of lines of code", but had no concrete evidence to prove it. After a quick google search I came to this stack overflow question, and the awesome answer(s) therein. 

If you were using an older version of angular CLI before it had aot built into it then you may start to receive these errors when you run you usual `ng serve` or `ng build` commands:

ERROR in Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function (position 7:3 in the original .ts file), resolving symbol mainStoreReducer in /.../, resolving symbol AppModule in /../, resolving symbol AppModule in /../, resolving symbol AppModule in /../

I just had the awesome opportunity to TA and sit in on a 2-day Angular 2 course instructed by one of the top teachers in the web development world and the hungry mind behind One Hungry Mind Blog, Lukas Ruebbelke (@simpulton). It was especially humbling because his eggy bookmarks course was one of the very first times I really dug in and started writing Angular code. It felt like meeting a childhood hero or Santa Claus. I had spent so much time watching his videos that it was surreal to meet him in person, and yes he is really that goofy and funny in real life. haha. Anyway, even though I have been using Angular 2 for a little while now and the course was aimed more for beginners, I still took about 4 pages of notes and learned a ton while I was there. Plus, it was great to get a refresher/confirmation on some basic concepts and some new perspective on how to think about certain other things. In this post I've written a bullet point list of some after-the-fact thoughts while looking back at the notes I took during the lectures. Enjoy!

If you've taken a look at some open source projects that use Ngrx such as example-app, ngrx-examples , or angular-nye-advanced-ngrx then you may have noticed that they have an interesting way of defining Action types. In this post I'll go over why we use the "type" method and why we construct the Action strings in this specific style. Big thanks to Xavier, @xlozingues, for staying at the office late on a Friday to help me understand this. ? ​
