How To Check If a Number Is a Single Digit in JavaScript

Checking whether a number is a single digit is a basic operation in programming. It is essential to determine whether a number has only one digit or not. In this tutorial, we will discuss how to check if a number is a single digit.

Steps:

Step 1: Get the input from the user

The first step is to get the number from the user. This number can be input by the user through a form, or it can be hardcoded in the program.
