This project contains two challenges - a "Ticket Breakdown" challenge and a "Refactoring" challenge. The two challenges are unrelated, but you should complete both in the same folder and share the link in Coderbyte. Any written answers should be included in markdown files within this folder.

Ticket Breakdown

Refactoring

If you are a JS novice, here's how to get started:

1. Install Node.js (we use ^16, the latest LTS)
2. Run npm i in this repo to install dependencies
3. Run npm test to run the automated tests
4. Run npm start to launch index.js for any manual testing

Logic

I did a litte re organization of the code, more related with the grouping of it, I preffer to have sections of code grouped with one objetive, for example the change that I did on this if

    if (candidate) {
        if (typeof candidate !== "string") {
        candidate = JSON.stringify(candidate);
        }
    } else {
        candidate = TRIVIAL_PARTITION_KEY;
    }

As you can see, this If clause was doing an action between 2 different verifications, in one side, it was ensuring that the type of the input was the correct one, and in other, it was defining what happens if not input was given. So I preffer to have a more understandable tree of options by defining the general logic first (if an input is given) and then the more specific logic (the value for the candidate in each way). Like this:

    if (event) {
        candidate = event.partitionKey ? parsePartitionKey(event.partitionKey) : encodeData(event);

    } else {
        candidate = TRIVIAL_PARTITION_KEY;
    }

I also made some complementary functions to help the reader to understand the objetive of each part of the code, by using a declarative name like encodeData, isNotValidEncondig, parsePartitionKey, in that way, future developer can easely modify the code if something fails/changes.
