web applications - javascript webapp development -

-

i confused web application development. read w3 , apple choose , recommend javascript developing web apps heard developing web apps need create back-ends java. can learn html5/css3/javascript , develop complete webapps using technologies?

thanks

think of circle. backend language, php, asp (.net) java, etc exists backend build frontend. html, javascript, css frontend. sure, can website solely in html , css, without backend code, we'd building pages static. user interacts application, goes server , processed , on , forth....hence circle.

html can't talk directly database, essential apps out there. hence reason it's near impossible away back-end development.

i've worked in java shop before...the reason many big operations use because it's considered in many circles "enterprise grade" government, banks, perhaps apple rely on power corporate apps , websites in many cases. java basis other languages, , structure , nuances copied in many other systems. 1 can make lot of money programming it.....but having been there, know can bloated, fickle, , inefficient. java not javascript.
