DAZN BE coding test (part 1)

DAZN BE Coding Test (part 1)

Background

We have a service that receives events. Each event consists of a fixture record, which is a JSON object representing a sporting event (e.g., a football match) for a specific language (therefore one sporting event will have many fixture records).

For example:

{
  "fixtureId": "xyzde",
  "name": "Benfica v Bayern München",
  "languageCode": "de",
  "competitions": [
    {
      "competitionId": "abcen",
      "languageCode": "en",
      "competitionName": "English League"
    },
    {
      "competitionId": "abcde",
      "languageCode": "de",
      "competitionName": "Englische Liga"
    }
  ]
}

As you can see, each fixture record also contains a list of competition objects, one for each language that the competition is available. Each competition object contains a competition ID, a language code and the translated competition name.

There may be a competition name matching the language of the fixture, but there is always an English translation.

The Task

You should implement a function that accepts a fixture record, and returns a FixtureWithTranslation object.

This object should contain the Fixture Id, Fixture Name and the Fixture's language code; As well as the competitionId and the matching translated Competition Name.

If there isn't a matching translation, the English Competition name should be used.

You should also implement any interfaces that are necessary, referring to the unit tests.

All Unit tests in task-1.test.ts should pass.

Expected output

We would expect the FixtureWithTranslation object for the above example to look like this:

This is covered in tests too.

{
  "fixtureId": "xyz",
  "languageCode": "de",
  "name": "Benfica v Bayern München",
  "competitionId": "abc",
  "competitionName": "Englische Liga"
}
