What are the prospects for HTML5 gaming on mobile devices?

Question

JavaScript

Hello comrades!
Short version of the question: suppose there is a simple game (TD genre, without particularly colorful graphics) written in HTML5 for PC. What will be its prospects for mobile devices? At the level of "fix a couple of places and it will be ok", "it will inevitably slow down" or "a normal HTML5 game on a tablet is a myth, you need to rewrite it natively"?
Detailed version of the question:
There is a person (me) who has dreamed of writing a game since childhood. From childhood, I was fond of programming - at an amateur level, jumping from language to language, without a serious understanding. The only "gamedev" project I completed was a Delphi clone of Lines.
I entered the institute as an engineer, I did not plan to connect my life with programming. However, life decided otherwise and contacted itself - I had to leave the "real" university for distance learning, and find a job as a coder - also, remotely.
Now I'm a Ruby on Rails junior and I love my area. However, on the one hand, the dream of making games does not disappear, and on the other hand, more and more often my work requires not only knowledge of Ruby, but also JavaScript - and now I have an idea to kill two stones with one hare, and pump up JS at the same time, and write something playful.
I have the main idea of ​​the game, and it fits perfectly not only on the computer screen, but also on the tablet. But there is one thing that worries me - will the HTML5 game be playable on a mobile device? Does it make sense to think about this topic?
And one more, side question - please advise resources on HTML5-GameDev? I don't mean articles per se, but places (forums/collective blogs/etc.) where you can chat with the same HTML5-GemeDev-sheep. It is possible in English.

Answer 1

"kill two stones with 1 hare" sorry what?
In general, it is very laggy. Niche html5 is customers.

Answer 2

It all depends on the specific task, what can be done, and what can not. But in general, development for android on html5 is a separate topic in which there are many nuances.
If there is a desire to participate in a game project and pump up js, I can offer to participate in my project, which I do for fun and do not pursue any commercial benefit.
