How to find the length of a JavaScript Number?

Estimated read time 1 min read

The length of a number in JavaScript can be calculated by converting the number to a string and then finding the length of that string. Here’s an example of a function that calculates the length of a number:

function numberLength(num) {
  return num.toString().length;

const result = numberLength(123456);
console.log(result); // 6

In this example, the toString method is used to convert the number num to a string, and then the length property is used to find the length of the string. The result of the function is the length of the number.
