What is server side java script? Can we use java script also at server side? Which type of java script is necessary to know for a front-end developer?

Question

I just read that there is also a type of java script called server-side java script, before it i was thinking that java script is used only at client side....so my question is what is server-side java script ...and for a front-end develoer , is it necessary to learn both types of java script?

Answer 1

Server side java script is somehow like java/C++/.Net/ruby/php... It is just an approach of programming server code. If you work on the front-end without any back-end work to do, it is not necessarily to learn server-side java script. Server side java script you mentioned is probably nodejs. Imagine that you can write a server with js instead of java or php.
