How competitive are Android apps built with HTML/CSS/JS?

Question

JavaScript

I learned about such an interesting way to convert html / css / js code into an application for ... . And the question immediately arose whether there was a big difference in the performance of such applications compared to applications in Java.
I'm interested in 1. With regards to simple applications, for example, an application with which you can order pizza and even select several pizzerias in the city. 2. Games
PS I understand that making games in html/css/js is a bit rude, but I'm only interested in problems on the user's side, for example, can the application work worse just because it is not written in Java, but in the above way.

Answer 1

For the application you describe, html / css / js is perfect. Since it is small and the drop in speed will not be noticeable. In general, all these engines are growing in performance every month, and soon even games, it seems to me, everything can be done on them and it will be no worse if you used java. Not of course, everything was faster in java. But development speed. After all, on these engines you can immediately publish your application for all platforms.
My verdict. To create medium-sized applications, you can use it, for complex and games I would not recommend it yet. In any case, soon it will be usual for us as now c++ vs c# or assembler vs c++. well, you understand)

Answer 2

Maybe you should really start writing a book? This is the 3rd pointless question in the last hour.
To compare the capabilities of html + js + css VS Java, you need to at least know what it is!
