🧩 JavaScript Basics — Homework (Tasks 1–4)

This repository contains my JavaScript Basics Homework, which includes four fundamental programming exercises focused on functions, conditions, and logical structures.

Each task was implemented in a separate JavaScript file and tested with console outputs for verification.

✅ Homework Tasks Overview

Task	Topic	Description
Task 1	Functions & Conditions	Calculate total order cost and check balance
Task 2	String Manipulation	Format text based on maximum length
Task 3	String Search	Detect spam words regardless of case
Task 4	Switch Statement	Return shipping cost or error message

⚙️ Task 1 — Droid Orders

File: task-1.js

Function: makeTransaction(quantity, pricePerDroid, customerCredits)

Goal: Simulate the purchase process for repair droids. The function should:

Calculate the total cost: quantity * pricePerDroid

Compare with available credits

Return:

• "Insufficient funds!" if total > credits

• "You ordered <quantity> droids worth <totalPrice> credits!" otherwise

Example Output:

You ordered 5 droids worth 15000 credits!

🧠 Task 2 — Message Formatting

File: task-2.js

Function: formatMessage(message, maxLength)

Goal: Ensure the message doesn’t exceed the given character limit.

Logic:

If message length ≤ maxLength, return unchanged

Otherwise, cut it to maxLength characters and add "..."

Example Output:

formatMessage("Curabitur ligula sapien", 16);
// "Curabitur ligula..."

🕵️‍♀️ Task 3 — Spam Check

File: task-3.js

Function: checkForSpam(message)

Goal: Detect forbidden words "spam" or "sale" (case-insensitive).

Logic:

• Convert message to lowercase using .toLowerCase()

• Return true if message includes "spam" or "sale"

• Return false otherwise

Example Output:

checkForSpam("Get best sale offers now!");
// true

🚚 Task 4 — Shipping Cost (Using Switch)

File: task-4.js

Function: getShippingCost(country)

Goal: Return the delivery price for the given country using a switch statement.

Country	Shipping Cost
China	100 credits
Chile	250 credits
Australia	170 credits
Jamaica	120 credits

If the country isn’t listed: Return "Sorry, there is no delivery to your country".

Example Output:

getShippingCost("Australia");
// "Shipping to Australia will cost 170 credits"

🧱 Concepts Practiced

✅ Function declaration & parameters

✅ Conditional statements (if, else, switch)

✅ String methods (length, slice, toLowerCase, includes)

✅ Template literals for formatted outputs

✅ Console-based debugging and testing
