Recursion example in JavaScript to display numbers is descending order?

You can call the same function again and again with some base condition called recursion. Following is the code −

Example

function recursiveFunction(num) {
   console.log(num);
   if (num > 0) {
      recursiveFunction(num - 1);
   }
}
recursiveFunction(5);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo304.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo304.js
