Project Title: The Smart Personal Assistant (BPA)

Project Overview:

• You are to act as a Junior Software Developer to create a functional 'Smart Personal Assistant' web application.
• The app must interact with the user, store preferences, and perform calculations based on their input.
• Choose one of the following STEM themes for your assistant:
  1. Health Assistant: Calculates BMI and gives health advice.
  2. Finance Tracker: Calculates savings/expenses and gives budget warnings.
  3. Academic Tutor: Calculates average scores and gives grade remarks.

Technical Requirements:
A. JavaScript Objects (Week 2)

• Represent a user as an Object with properties like firstName, lastName, age, and role.
• Include a Method (function inside the object) called welcomeMessage that returns a personalized welcome message.

B. Form Validation & Security (Week 3)

• Create a "Sign-In" or "Data Entry" section.
• Empty Field Check: Ensure no fields are left empty.
• Email Validation: Use a Regular Expression (Regex) to ensure the email format is correct.
• Alerts: Use alert() to notify the user of successful submission.

C. Browser Environment & Cookies (Week 3 & 4)

• Cookies: Use document.cookie to remember the user's "Theme Preference" (e.g., Dark Mode or Light Mode) even after the page is refreshed.
• Window Object: Use window.onload to trigger a "Welcome" sequence when the app starts.

D. Control Statements & Logic (Week 6)

• Use if-else or switch statements to make decisions.
• Condition 1: Based on a numerical input (e.g., Score, BMI, or Expense), display a specific remark (e.g., "Excellent", "Overweight", or "Over Budget").
• Condition 2: Change the UI color or text based on the result.
