Fast is relative. You may have a very good and fast algorithm on server, but you got bad network infrastructure, it'll look slow to the client. You may have a very poor algorithm on JS code, but you got good network infrastructure, and most of the clients are using high-end machine, it'll look quite fast to the client. Most clients would never care whether you put the code in server or in browser, the just want to use your application with acceptable and reasonable performance. Today web technologies are getting more advanced, internet connection is getting cheaper, browsers performance are getting better, web standards are getting more obeyed, and client machines are getting faster. Of course, nobody would prevent you to do all the computation on the server side. But IMO you'll waste resources on the client side that you may utilize. Though it doesn't seem to be significant when you look at a single client, but when you got thousands of clients connected, you would save significant resources on the server side. > Each user action can be transform to server, computed and results sand > back to browser.

But you could have more than just GUI on current JS frameworks and browser capabilities. Though it's not easy, but it's possible now to create a very complex desktop-like application on browser with acceptable performance. I never thought that I would see chess game to be completely running under browser using JS (no flash, no plugins, no applets, no server side logic is required). But it's common to see it or other kind of games under browser nowadays (with most or all of game logic resides on the browser side). -- -Bee- has Bee.ography at: http://beeography.wordpress.com _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
