Is it usefull to learn both php and java script or java script only will be enough

Answer 1

Depends on what you want to do. Javascript is enough (plus HTML and CSS of course) to make good responsive static webpage but PHP is needed for server-side proggraming.

Answer 2

khaled hammami absolutely no. node.js is very similar and created for this implementation as server-side.

Answer 3

Thank u ;
I mean server side programming can't be done with java script ??
