JavaScript survey: Devs love a bit of React, but Angular and Cordova declining. And you're not alone... a chunk of pros also feel JS is 'overly complex'

Re: JavaScript is "overly complex".

not so much sandboxing, but sanitizing. A good sanitizing algorithm will eliminate the possibility of SQL injection, as one example...

my favorite is to look for ';' and '/' (or quotes, or path starts with '..' etc. - or SQL keywords if that's at issue) and just reject things outright that contain these characters/sequences. Others also exist. simple test. PHP script has some other built-ins as well.

the only reason you would NOT want to do everything server-side is performance latency [when the server is across the world, let's say, or the bandwidth stinks]
