/*******************************************************************************
 These tasks will provide you with an opportunity to practice creating and manipulating variables,
 as well as using string concatenation and getting familiar with different datatypes.
 // Have fun! //😃
********************************************************************************/

/*******************************************************************************
 Task 1 (Variables):
 
 Steps:
    1. Create three variables named 'personName', 'age', and 'isHappy', where:
        - 'personName' should hold a string value
        - 'age' should hold a numeric value
        - 'isHappy' should hold a boolean value.
    2. Use console.log() to output the value of each variable.
 ********************************************************************************/
// TODO: ADD YOUR CODE BELOW
let personName = "ali";
let age = 20;
isHappy = true;
console.log( personName + " "+ age +" "+ isHappy);



/*******************************************************************************
 Task 2 (Reassigning variables):
 
 Steps:
    1. Create a new variable named 'nickName' and assign the value of the 'personName' variable to the 'nickName' variable.
    2. Use console.log o output the value of 'nickName'
 *******************************************************************************/
// TODO: ADD YOUR CODE BELOW
let nickName = personName
console.log("Nickname:" , nickName)

/*******************************************************************************
 Task 3 (Naming variables):
 
 Steps:
    1. Create a variable with the title of your favorite movie. How would you name such a variable?
    2. Declare a variable that stores the age of a user. What name would you choose for this variable?
*******************************************************************************/
// TODO: ADD YOUR CODE BELOW
MyFavoriteMovieTitle= "The Dark Knight";
userAge=" 30 years Old";

/*******************************************************************************
Task 4 (String Concatenation):
    Build upon the previous task by completing the following steps:

Steps:
    1. Declare a new variable called 'msg'.
    2. Use the `prompt()` function to ask the user to enter a message for the person you just created. Then assign the value to the `msg` variable.
    3. Use string concatenation to create a message
        - If 'isHappy' is true, add the question "And btw, Why are you happy?" to the message.
        - If 'isHappy' is false, add the response "And btw, Good for you. There's nothing to be happy about." to the message
        - Assign the completed message to a variable called finalMsg
        - Print the final message to the console, including the personName in uppercase in this format `Dear personName_VALUE, here's your message: finalMsg_VALUE.`.
*******************************************************************************/
// TODO: ADD YOUR CODE BELOW

let msg;
msg = prompt("Enter a message for the person:");

if (isHappy)  {
let isHappy = true;

msg += " And btw, why are you happy?";
}
if (isHappy) {
msg += " And btw, why are you happy?";
} else {
msg += " And btw, Good for you. There's nothing to be happy about.";
}

let finalMsg = msg;

console.log(`Dear ${personName.toUpperCase()}, here's your message: ${finalMsg}.`);
