High Scores

Challenge Overview

Given a string of digits, output all the contiguous substrings of length `n` in that string in the order that they appear.

Instructions

Manage a game player’s High Score list.

Your task is to write methods that return the highest score from the list, the last added score and the three highest scores.

Our Solution

export class HighScores {
  constructor(scores) {
    this.scores = scores;
  }
  get latest() {
    return this.scores[this.scores.length - 1];
  }
  get personalBest() {
    return Math.max(...this.scores);
  }
  get personalTopThree() {
    return [...this.scores].sort((a, b) => b - a).slice(0, 3);
  }
}
