Answer 1

  const anchor = require("@project-serum/anchor");

  // provider is an abstraction of a connection to solana 
  const provider = anchor.Provider.local();
  anchor.setProvider(provider);
  const switchAccount = anchor.web3.Keypair.generate();
  // initial letter must be capital letter
  const program = anchor.workspace.Yourdappname;
