let color = 'white';
let char = 'active'
let age = 3;

function getCatInfo(color, char, age) {
  return `${color} cat is ${char} and ${age} years old.`;

let myCat = {
  color: 'white',
  char: 'active',
  age: 3,
  getInfo: function() {
    return `${this.color} cat is ${this.char} and ${this.age} years old.`;
