Help on Web3.js

Is it possible to run a javascript on server side on perpetuity?

I saw web3.js have a watch function that is always looping. However, most of the time i see it used on websites, but not server side.


How can I run a javascript on server side continuously so i can use the watch function in web3.js?

You can run javascript perpetuity on server side, you need an JS engine to do it. It can be a headless browser with a JS engine, a server like node,js using the V8 js engine, or Rhino/Nashorn JS engine running inside a JVM. But the context at which they run will be different from the context of your JS running inside your browser. One is client side and one is server side. The only one i mention above is working as a client side is automating a server side headless browser.
