number of digits in javascript

To find the number of digits in a number using JavaScript, we can convert the number to a string and count the number of characters in the string. Here's an example code snippet:

index.tsx
let num = 12345;
let numString = num.toString();
let numDigits = numString.length;
console.log(numDigits); // output: 5
120 chars
5 lines

In this code snippet, we first declare the number 12345. We then convert this number to a string using the toString() method, which gives us the string "12345". We assign this string to the variable numString. Finally, we use the length property of the string to get the number of characters in the string, which gives us the number of digits in the original number.
