About Exercise

1. Write a function that when we call that function console.log(), similar to the given example, it will give us a string about the information of that object.

const user1 = {
    name: "Jasem",
    lastName: "Amiri",
    age: 10
}
const user2 = {
    name: "Admad",
    lastName: "Ghasemi",
    age: 22
}
const user3= {

    lastName: "Ahmadi",
    age: 7
}
const user4 = {
    name: "Mina",
    lastName: "Mohseni",

}

// mesali as khoroji function => "Ahmad Ghasemi is 22"
console.log(introductionTheUser(user1))
console.log(introductionTheUser(user2))
console.log(introductionTheUser(user3))
console.log(introductionTheUser(user4))

2. Write a function that returns the last character from the string. Note: Under no circumstances should the 'undefined' log be taken Write a warning or error instead.
