1.20 – Simple Interest & Rectangle Program | Full Execution | New Series

Описание: Welcome to the JavaScript for MERN Developers – Job-Ready Series (New Series) by Burle Sharma.

In this class (1.20), we solve the first two questions from the previous practice set with complete explanation.

In this session, I have:

🔹 Written the expected output first
🔹 Explained the formula clearly
🔹 Written the complete program
🔹 Executed the program step-by-step

This helps students understand how mathematical formulas are converted into proper JavaScript logic.

📚 Programs Covered in This Video:

🔹 1. Write a program to calculate Simple Interest

Formula used:
Simple Interest = (Principal × Rate × Time) / 100

🔹 2. Write a program to calculate Area and Perimeter of a Rectangle

Formulas used:
Area = Length × Breadth
Perimeter = 2 × (Length + Breadth)

🎓 What You Will Learn:

✅ How to apply formulas in JavaScript
✅ How to write clean input and output logic
✅ Importance of expected output before coding
✅ Step-by-step execution method
✅ Strengthening arithmetic operator concepts

🧠 Key Learning Point:

Before moving into selection statements (if–else), your formula-based logic must be strong.

These programs build confidence in:

✔ Mathematical calculations
✔ Variable handling
✔ Execution understanding
✔ Clean program structure
