Hello Guys Im beginner. What are the advantages/disadvantages of using Javascript as server than using PHP?

Answer 1

If you mean NodeJS as a JavaScript server is simple - PHP is faster, more tested and have a lot of more users (which means more documentation and existing libraries/applications).
But I can not predict the future - NodeJs is growing fast.

Answer 2

personally i think PHP is more intuitive than node.js, even though JavaScript is more intuitive as a language.
