JavaScript Strings Popcorn Hacks & Homework

Popcorn Hack #1 - Secret Password

Instructions:

Create three string variables named secretBase, codeWord, and symbol. • Each should contain text inside quotes (“ “ or ‘ ‘).
Find the number of characters in the secretBase string. • Use the .length property to count how many characters are in the string. • Store this value in a new variable called baseLength.
Change all the letters in the codeWord string to uppercase. • Use the .toUpperCase() method and store the result in a variable named fullCode.
Combine all the strings together to reveal the full secret message. • Use the + operator to concatenate secretBase, fullCode, and symbol. • Save it to a variable named fullSecret.
Print your results using console.log(). • Display both the string length and the full secret message in the console.

%%javascript


// Task 1: Create your variables

let ____ = "__________ ";
let ________ = "__________ ";
let __________ = "______";

// Task 2: Find the number of characters in the first string.
let baseLength = ____.length;

// Task 3: Standardize the second string to all uppercase letters.
let fullCode = ________.to_______Case();
// Task 4: Combine everything to reveal the full secret.
let fullSecret = ____ + fullCode + __________;

// Task 5: Print the results.
console.log("___________");
console.log(baseLength);

console.log("__________");
console.log(fullCode);

Popcorn Hack #2 - Grocery Store

Instructions:

Define your variables and string values • Each should contain text inside quotes (“ “ or ‘ ‘). • Your variables should include: ingredient, price, and store.
Write a message using template liberals. • Using mlti-line strings and interpolation, create a complex sentence writing an automated message advertising a discounted item. • Use backticks!!
Use interpolation to check the amount of characters in the lesson! • Use ${} and .length to help.
Print your results using console.log(). • Display both the string length and the full secret message in the console.

// Task 1: Define your variables and strings

let _____ = "______ "; 
let ______ = "______";
let _______ = "______";

// Task 2: Write the complex sentence using a template literal (backticks).
// Use ${} to insert the variables directly.
const snackMessage = `

`;

// Task 3. Check the length of the full message and print it to the console.

console.log(`The full message is ${_______} characters long.`);

console.log(snackMessage);

Homework

Objective: Apply string concepts (const, quotes, .length, .toUpperCase(), and template literals) to format game data.

🏷️ Part A - String Variables & Quotes

Create a constant variable named UPGRADE_NAME and assign it the string value "Lucky Seven". Print this variable to the console.

Create a variable named cost and assign it the number value 7777. Print this number to the console.

Create a variable named EMOJI and assign it the emoji string value “🍀”.

Create a variable named BUTTON_CLASS and assign it the string value: bg-green-500 hover:bg-green-600 text-white.

📏 Part B – Length and Modification

Using the UPGRADE_NAME variable from above, create a new constant variable named DISPLAY_NAME that converts the name to all uppercase letters. Print DISPLAY_NAME.

Create a constant variable named NAME_LENGTH that stores the total number of characters (including spaces) in the original UPGRADE_NAME. Print the length to the console with a label like: “Name Character Count: [Count]”.

Create a variable named message that stores the exact string below.

“Insufficient Cookies”

✨ Part C – Template Literal Interpolation

Use string concatenation (the + sign) to combine the EMOJI, UPGRADE_NAME, and cost variables into the following exact output. Print the result. Challenge (extra credit): Use String Interpolation

🍀 Lucky Seven (7777 Cookies) Now, rewrite the entire message from problem 8 using a template literal (backticks `) and interpolation (${}). Store the result in a new variable called shopButtonText. Print shopButtonText.

The Final Message: Create a constant variable named errorDisplay that uses a template literal to combine the following three variables into one clean message: EMOJI, UPGRADE_NAME, and message.

Error: 🍀 Lucky Seven purchase failed: “Insufficient Cookies” Hint: The quote marks around Insufficient Cookies must be part of the final output string.

🌟 Extra Credit Challenge (Optional) Create a variable named HINT_TEXT that stores the following exact quote: The “Lucky Seven” upgrade multiplies your clicks by 7.
