Stats Display of Averages of Carrier per Star Metric

[Tsangares]

There are a few star related metrics. I would like to know and have displayed to me:

• Mean, median and minimum and maximum of Carriers Per Star. In JavaScript we should create a map-key data structure where the keys identify each hero-owned star and the value is the number of carrier that have that star in their rote; this datastructure will be referred to as the galactic_metro. One method to calculate this, for each carrier and for each star in the route of that carrier increment the galactic_metro by one and keep a list of each star this carrier has incremented; if the carrier has already incremented this star then continue. The procuring the mean, median, minimum and maximum are straight forward: convert galactic_metro to a vector of the number of carrier that have this star in their route.
• Another interesting similar metric is the total amount of natural resources
• Other metric: Carriers Path length mean, median, min, max, std

Median

Function to get the median in typescript:

function calculateMedian(numbers: number[]): number {
  numbers.sort((a, b) => a - b);
  let middle = Math.floor(numbers.length / 2);
  return numbers.length % 2 !== 0 ? numbers[middle] : (numbers[middle - 1] + numbers[middle]) / 2;
}

Minimum and Maximum

Wrappers for minimum and maximum:

function getMinimum(numbers: number[]): number {
  return Math.min(...numbers);
}

function getMaximum(numbers: number[]): number {
  return Math.max(...numbers);
}

Mean

Snippet for mean

function getMean(numbers: number[]): number {
  let sum = numbers.reduce((a, b) => a + b, 0);
  return sum / numbers.length;
}
