Solidity contract run script explained

run.js

 * We require the Hardhat Runtime Environment explicitly here. This is optional
 * but useful for running the script in a standalone fashion through `node <script>`.
 * 
 * When running the script with `npx hardhat run <script>` you'll find the Hardhat
 * Runtime Environment's members available in the global scope.
 * 
 * Check: https://hardhat.org/guides/scripts.html#standalone-scripts-using-hardhat-as-a-library

   *   manually to make sure everything is compiled
   *   await hre.run('compile');
