Recursive product of all digits of a number - JavaScript
We are required to write a JavaScript function that takes in a number and finds the product of all of its digits. If any digit of the number is 0, then it should be considered and multiplied as 1.
For example − If the number is 5720, then the output should be 70
Example
Following is the code −
const num = 5720;
const recursiveProduct = (num, res = 1) => {
if(num){
return recursiveProduct(Math.floor(num / 10), res * (num % 10 || 1));
}
return res;
};
console.log(recursiveProduct(num));Output
This will produce the following output in console −
70
