Here's my code

var fName = prompt("Enter your first name"); var str_fname = fName.length; var lName = prompt("Enter your last name"); var str_lname = lName.length; var space = " ";

var name = fName.toUpperCase()+ space + lName.toUpperCase(); var str = str_fname + str_lname; console.log(str);

var message = "The string " + name;

message += " is " + str + " characters long."; alert(message);

Nice but about this part:

var str_lname = lName.length; var space = " ";

It's better put the variables in two separate lines for less mess.

Anyway this is my solution

var questions = [
  "what's your name?",
  "what's your surname?"
];

function presentation() {
  var name = prompt(questions[0]);
  var surname = prompt(questions[1]);
  var sum = name.concat(surname);
  var message = "Welcome " + name.toUpperCase() + " " + surname.toUpperCase() + ". Your name is long " + sum.length + " letters.";
  return message;
}

alert(presentation());

Whoa, Cosimo, I love how you organized your solution! I had no idea how to insert more than one action in a function; actually, it didn't even cross my mind that we could.

Here's my solution:

var firstName = prompt("What is your first name?");
var lastName = prompt("What is your last name?");

var fullName = firstName.toUpperCase() + " " + lastName.toUpperCase();
console.log(fullName);

var nameLength = fullName.length;
console.log(nameLength);

alert("The string " + fullName + " is " + nameLength + " characters long.")

Hi Guys! Here's my code:

let firstName = prompt("What is your first name?");
let lastName = prompt("What is your last name?");
let fullName = (firstName + " " + lastName).toUpperCase();
let nameCharLength = fullName.length;
alert("The string '" + fullName + "' is " + nameCharLength + " characters long.");

Hi, your answers are good but you miss to add the doudble quote around the name like in the video

var firstName = prompt("What is your first name");
var lastName = prompt("What is your last name");
var fullName = (firstName +" "+ lastName);
var fullName = fullName.toUpperCase();
console.log(fullName.toUpperCase());
console.log(fullName.length);
var fullNameNumber = fullName.length;
alert("Your name \"" + fullName + "\" contains " + fullNameNumber + " Characters");

This is how i did it, and i have added few extras at the end.

var firstName = prompt("What is your first name ?"); var lastName = prompt("What is your last name ? "); var fullName = firstName + lastName ; var nameLength = fullName.length; alert ("the name " + fullName + " is " + nameLength + " characters long " ); document.write("the name " + fullName + " is " + nameLength + " characters long " ); document.write("Mohamed is geneius, he is loving javascript ");

I'm not sure if I am missing anything but I thought that I would share my solution as well.

var input1 = prompt("Enter an input");
var input2 = prompt("Enter another input");

uppercase = input1.toUpperCase() + " " + input2.toUpperCase();
alert("The string " input1.toUpperCase() + " " + input2.toUpperCase() " is " + uppercase.length + " number of characters long.");

Here's My code:

// First and second question for the user:
const question1 = prompt("What is your favorite animated show?");
const question2 = prompt("What is the name of your favorite character from that show?");

// Combine the answers into one string. Include a space inbetween
const combinedAnswer = `${question1.toUpperCase()} ${question2.toUpperCase()}`;

// Find the length of combinedAnswer and store it in a variable
const lengthOfAnswer = combinedAnswer.length;

// Type it into the statement: 'The string "___" is __ characters long.'
// Than display it as an alert pop up
const yourInput = `The string "${combinedAnswer}" is ${lengthOfAnswer} characters long. `;
const finalAlert = alert(yourInput);
