Does HTML5 make Javascript gaming safer (more secure)?

I know that Javascript is an incredibly unsecure way of programming a persistent game, where for instance you are doing battle calculations in an RPG and then award XP through linking to a PHP page when they win that adds XP to a database (since the player could make their own javascript to always win o开发者_如何转开发r just look at the PHP page that you get sent to when you win and just go there anyway).

So with that said, I'm wondering if HTML5 makes multiplayer/persistent games any safer in this regard, since I know it still uses Javascript. Or am I still doomed to rely entirely on server-side scripting for doing any calculations that award the player?

Anything that's not on the server is inherently insecure. After all, it only takes a telnet connection and the user can send literally anything they want to your server.

In short, you can't trust anything sent from the client, so the answer is yes - you gotta do the work on the server side.

Unfortunately, HTML5 doesn't change these basic properties in any way. So no, you have to do it all server-side.

No matter what the game, whether JS or native binary, if the scoring system is vulnerable, people will tamper if the game is good enough. Stick to clever serverside every time.
