// что такое строковый шаблон? привести пример
// 1) создаем идентификатор  и назовем его  welcome
// 2) передаем аргумент person котоый будет принимать объект с именами
//3 в консоли вызываем аргумент person со свойством name т.е
// под person подстваится объект marcus а name это свойство объекта 'Marcus'
const welcome = person =>{//1
  console.log(`Ave, ${person.name}!`);//Ave, Marcus
};

//объекты
const marcus = {name:'Marcus'};
const mao = {name:'Mao'};
const cartesius = {name:'Rene'};

//вызов функции
welcome(marcus);//передаем ссылку на объект

//переделаем через массив
// чем отличается for of от for in?
const welcome = person =>{
  console.log(`Ave, ${person.name}!`);//Ave, Marcus,Ave, Mao, Ave, Rene
};

//example объекты
const persons = [
  {name:'Marcus'},
  {name:'Mao'},
  {name:'Rene'},
];

for(const person of persons) {//перебор массива persons
  //вызов функции
  welcome(person);
}

const welcome = person => {
  console.log(`Ave,${person.name}`);
};

const persons = {
  marcuse:{name:'marcus Aurelius'},
  mao:{name:'Mao Zedong'},
  rene:{name:'rene descartes'},
};


for(const name in persons){
  const person = persons[name];//в persons будут лежать ключи объекта marcuse{},mao{},rene{}
  // а свойствои объекта будут {name:'marcus Aurelius'} поэтому  persons[name] используем как ассоциативный массив где name это ключ

  welcome(person);
