JavaScript Program to Condense a Number

π Introduction
In the realm of programming, various tasks involve manipulating and transforming numbers. One interesting problem is condensing a number, which means reducing a number by summing its digits until a single-digit number is obtained. This process is often referred to as finding the digital root or digit sum.
In this tutorial, we will explore a JavaScript program designed to condense a given number. The program involves repeatedly summing the digits of the number until a single-digit result is achieved.
π Example
Let's delve into the JavaScript code that accomplishes this task.
<!DOCTYPE html>
<html>
<body>
<script>
// Function to condense a number
function condenseNumber(number) {
// Continue summing digits until a single-digit number is obtained
while (number > 9) {
let sum = 0;
// Sum the digits of the number
while (number > 0) {
sum += number % 10;
number = Math.floor(number / 10);
}
// Update the number with the sum
number = sum;
}
// Return the condensed number
return number;
}
// Driver program
// Replace this value with the number you want to condense
const number = 9875;
// Call the function to condense the number
const condensedNumber = condenseNumber(number);
// Display the result
console.log(`The condensed form of ${number} is: ${condensedNumber}`);
</script>
</body>
</html>
π» Testing the Program
To test the program with different numbers, modify the value of number in the code.
The condensed form of 9875 is: 2
π§ How the Program Works
- The program defines a function condenseNumber that takes a number as input and condenses it by summing its digits until a single-digit result is obtained.
- Replace the value of number in the main program with the desired number you want to condense.
- The program calls the condenseNumber function and prints the result using console.log.
π§ Understanding the Concept of Condensing a Number
Before delving into the code, let's understand the concept behind condensing a number. The process involves repeatedly summing the digits of the number until a single-digit result is achieved.
For example, consider the number 9875. The program would calculate 9 + 8 + 7 + 5 = 29, then 2 + 9 = 11, and finally 1 + 1 = 2. The condensed form is 2.
π’ Optimizing the Program
While the provided program is straightforward, consider exploring and implementing alternative approaches or optimizations for condensing numbers.
