3.15 – Sum of 1 to 10, Sum of 1 to N & Factorial using while Loop | JavaScript | New Series

Welcome to the JavaScript for MERN Developers – Job-Ready Series (New Series) by Burle Sharma. In this video (Chapter-03 | Class-15), we continue our while loop practice by solving three very important programming problems. 👉 The goal of this class is to strengthen your understanding of summation logic, accumulator variables, and multiplication-based calculations using while loop. These programs are frequently used as building blocks for many advanced programming concepts. 📚 Programs Explained in This Video 1️⃣ Write a program to display the sum of numbers from 1 to 10 2️⃣ Write a program to accept a number N and display the sum from 1 to N 3️⃣ Write a program to accept a number and display its factorial 🔹 Explanation Flow in This Video 🔹 Understanding the problem statement 🔹 Writing the logic step-by-step using while loop 🔹 Using accumulator variables for calculations 🔹 Performing detailed dry run for each program 🔹 Understanding loop execution and variable updates 🔹 Executing all programs to verify output 🎓 What You Will Learn 🔹 How to calculate sum using while loop 🔹 Difference between fixed-range and user-defined range programs 🔹 How accumulator variables work 🔹 How to calculate factorial using while loop 🔹 Strengthening loop-based problem-solving skills 🧠 Key Learning Point Most programming problems involving totals, counting, and multiplication use an accumulator variable. This class helps you understand: ✔ Repeated addition using loops ✔ Repeated multiplication using loops ✔ How variables change during execution ✔ The importance of dry run in logic building These concepts are used extensively in: ✔ Mathematical programs ✔ Data processing applications ✔ Interview coding questions #JavaScript #JavaScriptNewSeries #WhileLoop #FactorialProgram #SumOfN #JavaScriptPrograms #LearnJavaScript #MERNStack #BurleSharma #GeeCoding
