Build a Voting System

In this lab, you will build a voting system that uses `Map` to create a poll and `Set` to prevent duplicate voting. **Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab. **User Stories:** 1. You should initialize a `poll` variable to a new `Map` object. 2. You should have a function `addOption` that accepts a parameter `option`. 3. In the `addOption` function: - If the `option` does not already exist in the poll, it should be added to the poll with an empty `Set` as its value to track voters. You should also return the message `Option "<option>" added to the poll.` - If the `option` already exists, it should return the message `Option "<option>" already exists.` - If you try to add an empty option, the function should return the message `Option cannot be empty.` 4. You should have a function `vote` that accepts two parameters, `option` (the option to vote for) and `voterId` (a unique ID for the voter). 5. In the `vote` function: - If the `option` does not exist in the poll, the function should return the message `Option "<option>" does not exist.` - If the `option` exists, the function should check if the `voterId` has already voted for this `option`. - If the voter has already voted, the function should return the message `Voter <voterId> has already voted for "<option>".` - If the voter has not voted, `voterId` should be added to the `Set` of `voters` for this option. The function should return the message `Voter <voterId> voted for "<option>".` 6. You should have at least three options in your `poll`. 7. Your `poll` should have at least three votes. 8. You should have a function `displayResults` that returns the poll results in the following format: ```js Poll Results: OptionA: N votes OptionB: N votes . . /* sample output Poll Results: Turkey: 2 votes Morocco: 1 votes */ ```
