generation.js

// Try finding your ancestors and offspring with code.
// Create a function that takes a number and "m" (for male) or "f" (for female), and returns the name of an ancestor (m/f) or descendant (m/f).
// If the number is negative, return the related ancestor.
// If positive, return the related descendant.
// You are generation 0. In the case of 0 (male or female), return "me!".

// Examples:
// generation(2, "f") ➞ "granddaughter"
// generation(-3, "m") ➞ "great grandfather"
// generation(1, "f") ➞ "daughter"

function generation(x, y) {
  const main = {
    "-3": { m: "great grandfather", f: "great grandmother" },
    "-2": { m: "grandfather", f: "grandmother" },
    "-1": { m: "father", f: "mother" },
    0: { m: "me!", f: "me!" },
    1: { m: "son", f: "daughter" },
    2: { m: "grandson", f: "granddaughter" },
    3: { m: "great grandson", f: "great granddaughter" },
  };
