Congratulations on launching this. I see why you posted the 'history' page first, as it's obviously been a long story!

But from a visitor's perspective, I suggest you let the code tell the story.

Some code samples on the homepage would be very useful. Especially as, from the syntax, it looks like it isn't just another C-family language.

Thank you, I will do that.

To give you an idea how server code looks:

Here is an example for server code, just added a minute ago: https://xoscript.com/docs.xo?chapter=examples

I don't quite get what the language means by being pure object oriented since it seems to support varinle assignment and thus side effects?

it means there are objects, everything is an object. That has nothing to do with side-effects.
