Random average number service

• When the random average number service starts it calls a target service using recursion every one second https://csrng.net/csrng/csrng.php?min=0&max=100

• The target API returns an object that contains a random number [{ max: 100, min: 0, random: 23, status: success }]

• The random number is pushed in to a number list and the list of numbers are store in a promise

• When the random average number endpoint is called /random-average-number it takes the number list stored in the promise and builds a json response object

• The json response includes a list of the random numbers since the service started, a calculated average number and fixed average number {randomNumbers:[69,19,1,55],averageNumber:36,averageNumberFixed:36}

How to run

1. You will need the latest LTS version of Node JS 18.17.1
2. npm run build
3. npm run start
4. When you are ready you can go hit the service endpoint http://localhost:8005/random-average-number
5. You should see the average random number response{randomNumbers:[69,19,1,55],averageNumber:36,averageNumberFixed:36}
6. If you hit the endpoint again you will see an increment in the results
