Here is the problem. I have an object with property and value and I iterate through the object in order to get property and want to map this property with an array of qualityCharacter and after output I get this: ;;;;; instead of it: human ; Maksym ; male ; 2 ; 2 ; Hello world!
`
const inhabitants = {
  dog: {
    species: "dog",
    name: "Barsik",
    gender: "male",
    legs: 4,
    hands: 0,
    saying: "woof-woof!"
  },
  cat: {
    species: 'cat',
    name: 'Markiz',
    gender: 'male',
    legs: 4,
    hands: 0,
    saying: 'meow'
  },
  man: {
    species: 'human',
    name: 'Maksym',
    gender: 'male',
    legs: 2,
    hands: 2,
    saying: 'Hello world!'
  },
  woman: {
    species: 'human',
    name: 'Khristina',
    gender: 'female',
    legs: 2,
    hands: 2,
    saying: 'Hi world!'
  },
  catWoman: {
    species: "cat",
    name: "Murka",
    gender: "female",
    legs: 2,
    hands: 2,
    saying: ""
  }
};
inhabitants.catWoman.saying = inhabitants.cat.saying
// I try to iterate through object with for in loop.
const inhabitant = (species) => {
  for (let property in species) {
    const allSpecies = [];
    allSpecies.push(property);
    const qualityCharacter = ['species', 'name', 'gender', 'legs', 'hands', 'saying'];
    allSpecies.map(character => console.log(qualityCharacter.map(quality => character[quality]).join(";")));
  }
}
inhabitant(inhabitants);
