Hi thanks
I have a question for web3.js of ethereum
1 to run web3.js whether I must run Geth on the same server
3 whether I must run the fill node on the same server in order to run web3.js
3 web3.js is used to make a web application for ethereum token and contract?
4 web3.js cannot be used in the code of sol? Run in mist?

Thanks
