If FP refers to Functional Programming...

I think the concerns of DOP and FP are different. Maybe the comparison would be more OOP to FP.
As stated in the book's page at Manning, seems that the DOP aims to separate code and data to simplify state management and eases concurrency.

But I'm sure Yehonathan would clarify it better.
There is a similar question but about from Java 8 to Java 11. https://coderanch.com/t/739623/certification/OCP-Java-SE-Developer-Practice
Also, Scott shared a post with a recommendation about the Upgrade exam https://www.selikoff.net/2020/10/06/taking-the-1z0-819-exam-study-everything-and-watch-the-clock-part-2-of-2/
Check item #5. "1Z0-819 Exam vs 1Z0-817 Upgrade Exam: Scott’s Recommendation"

Can some people focus and self-discipline enough to ignore the million notifications constantly coming in not directly relating to what they are trying to learn?  Yes.


Totally agree. I got distracted very easily with unrelated things while watching/reading online material. But it is totally different when I read a book, even technical/programming books.
I know of some people that don't want to buy printed books because of the fear of "what people will say!"

I would say, drink water, fresh air and good sleep times helps better on learning stuff. Although not everyone can do it regularly.
You are right. I've been looking for insights on the Upgrade exam over the Web.

The Upgrade exam has the double of time and 61% passing score. Effectively the number of correct answers for passing the exams are:
- Upgrade exam: 49
- Normal exam: 34.
Thank you Scott, I appreciate your recommendation.
I found your post from March 2019 about your experience with the Java 11 exam.

Your impressions of modules remain the same with the new version of the exam (1Z0-819)? And the book reflects the same?
Hi Jeanne and Scott

I got Java 8 certified. Thanks to your book.
Do you recommend taking the Java 11 upgrade exam (1Z0-817) instead of the normal exam (1Z0-819)?
I see that the Java 11 upgrade exam has 30 questions more than the normal exam. In fewer topics than the normal exam, though.
Do you know what is the difference in terms of difficulty of the questions?
Can I also use the old Java 8 practice test book?

Are there practice tests from the Java 8 book that I should NOT use for passing the Java 11 exam? For example, I think the new feature of try-with-resources (now we can use previously initialized variables as parameters) might be conflicting from Java 8 to Java 11 exams. 
Or not?
I would say is an amazing focus.
Thank you Jamiel.

Hi Jamiel,
Congratulations on your new book.

How Corda is different to other libraries like BitcoinJ and HyperLedger?
Where Corda comes in play?

Thanks.

Yes, I was surprised to see a topic about iframes in your book. Seems to be more like why not to use it though  

I have not hear before about the services you mention (podium, zalando tailor). I'll check them out.

Thank you!
I would say that the decision whether to apply the micro frontend architecture should be taken from the beginning.
From what I see, micro-frontend involves the architecture of the project as a whole. So changing in a later stage from my traditional frontend approach to micro-frontend will cause to refactor a lot of things and this, in big project/team/company will need a whole set of regression testing, just for mentioning one.
But I think Michael Geers would have a better advice on this.
Hi Michael Geers,

How many approaches do you promote to accomplish the rendering of the micro-applications?
I can think of Ajax + container elements like DIV.
Wow, that's an amazing way of how to break the soft-class feature of Javascript. Although as you say, maybe "most programmers will prefer the class syntax".

I see this approach a bit complicated as the developer needs to take care of several things if he wants to do it right.

Anyways, it's always great to see how things can be done in a different way in Javascript.
Tahnks!
Cay,

In the Chapter 3, there is a "Hard Objects" topic.
It explains how to create Hard Objects in Javascript?

Thanks.
Congrats on the new book Cay.

This book, just as the name, follows the same teaching approach as the "Core Java SE 9 for the Impatient"?
It was really nice and effortless to read that book.
