Can i create a dynamic website without using js?

Question

If I can't then why?

Answer 1

Like Obama says: Yes, you can!

But, first, let's divide the explanation by 2:

1) Dynamic web pages generated on the server side:
you can develop on the server side, using languages like Java, PHP, etc, that generate and render, dynamicaly, the HTML and send to the view/front-end.

2) Dynamic web pages generated on the client side:
There are plugins like Shockwave Flash, Silverlight and Applet for Java that run application programaticaly on the client-side. All this things was discontinued and replaced by the HTML5 in parallel with JS, so it's not recommended anymore, but just exist. Although there are some options on client-side, the evolution of the web security and development, in general, bring us to JS, 'cause this language don't need plugins or anyelse more beyond the self browser to execute.
