TypeScript: solution failed online but passed locally.

Bug, timeout or some kind of change? Time took to run : 16.309 s.

const LETTERS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

const random = (min: number, max: number /* max is exclusive */) =>
  Math.floor(Math.random() * (max - min) + min);

export class Robot {
  private static names = new Set();
  private robotName: string = "";

  constructor() {
    this.robotName = Robot.generateName();
  }

  public get name(): string {
    return this.robotName;
  }

  public resetName(): void {
    this.robotName = Robot.generateName();
  }

  public static releaseNames(): void {
    this.names.clear();
  }

  private static randomLetter(): string {
    return LETTERS[random(0, 26)];
  }

  private static randomDigit(): number {
    return random(0, 10);
  }

  private static generateName(): string {
    let name;
    do {
      name = [
        Robot.randomLetter(),
        Robot.randomLetter(),
        Robot.randomDigit(),
        Robot.randomDigit(),
        Robot.randomDigit(),
      ].join("");
    } while (Robot.names.has(name));
    Robot.names.add(name);
    return name;
  }
}

Should have been solved! If not, please comment here again so we can re-open.
