WordPress Move to JavaScript

[techlists at phpcoderusa.com]

Hi,

This is kind of off topic, however WordPress is Open Source and I would 
expect that the vast majority of WordPress is run on LAMP servers.

My daily driver is a 10 year old Dell that has an i5 with 16G of RAM 
that runs Kubuntu 24.04lts.

I am running a blog using WordPress that is hosted on an Ubuntu server.

I am having issues with the WordPress Gutenberg back end.  I cannot get 
it to do the things I want to do like bold text. At times is is 
sluggish.  I've read that WordPress has a 10 year plan to move to 
JavaScript.  There is not a lot of info available so it is unclear if 
the PHP code will be replaced as well.  If WordPress replaces the PHP 
back end I will leave WordPress.  As it is WordPress is hanging by a 
thread.

These problems are new. I am also having formatting issues which might 
be due to my theme.

Is anyone having these issues or maybe other issues with WordPress?

Ultimately I may create my own infrastructure or start building my own 
theme.

Any feedback is very welcome.

Keith
