Hi,
here is my result of learning how and where else to use pas2js
It is huge topic, so in short, as I developed the code, I changed tactics and approaches to problems at least few times. For example you can use WCL Tab Components (if you installed it in Lazarus) but now writing an html template in whatever editor and then find and use only tags from this html documents for proceeding it further in pas2js it seems very useful way. To make controls on the website to look I used possibilities offered by pas2js instead of external css. And as always, reverse engineering (how is it done in js?)
