const person = { name: 'Lydia' };
function sayHi(age) {
return `${this.name} is ${age}`;
}
console.log(sayHi.call(person, 21));
console.log(sayHi.bind(person, 21));
//With both, we can pass the object to which we want the this keyword to refer to. However, .call is executed immediately!
//.bind returns a copy of the function, but with a bound context! It is not executed immediately.
