Describe alternatives you've considered Vanilla suggestion would be something like Source: https://github.com/you-dont-need/You-Dont-Need-Lodash-Underscore#_random

 //Native ES6
  const random = (a = 1, b = 0) => {
    const lower = Math.min(a, b);
    const upper = Math.max(a, b);
    return lower + Math.random() * (upper - lower);
  };

  const randomInt = (a = 1, b = 0) => {
    const lower = Math.ceil(Math.min(a, b));
    const upper = Math.floor(Math.max(a, b));
    return Math.floor(lower + Math.random() * (upper - lower + 1))
  };
