Creating a Ballot
// import the DBallot contract
const DBallot = artifacts.require('DBallot');
// deploy a new instance of the contract
const nextElectionDate = Date.now() + 100000; // 100000 seconds from now
const votingPeriod = 3600; // 1 hour
const ballot = await DBallot.new(nextElectionDate, votingPeriod);Adding Candidates
// add a candidate to the ballot
const partyName = 'My Party';
const description = 'A description of my party';
const logoUrl = 'https://my-party-logo.com';
await ballot.addCandidate(partyName, description, logoUrl);Creating a Ballot

const ballot = await DBallot.new(nextElectionDate, votingPeriod);Casting Votes
// cast a vote for a candidate
const candidateId = 0; // the id of the candidate to vote for
await ballot.castVote(candidateId);Retrieving Results
// get the results of the ballot
const results = await ballot.getResults();
console.log(results); // an array of candidate objects, sorted by vote countTry running some of the following tasks:
