Get the second digit of a number in JavaScript

In this tutorial, we will learn how to get the second of a number in JavaScript.

Getting the second digit of a number

To access the second digit of a number:

  1. Convert the number to a string.

  2. Call the charAt() method on it, by passing the second digit index 1.

  3. It returns the character at that index.

Here is an example:

const id = 13456;
const secondDigit = String(id).charAt(1);

// converting string back to number
console.log(Number(secondDigit));

Output:

3

The charAt() method accepts the character index as an argument and return its value in the string.

Similarly, we can also use the square brackets notation [] in JavaScript to get the second digit of a number.

Here is an example:

const id = 13456;
const secondDigit = String(id)[1];

// converting string back to number
console.log(Number(secondDigit));

Output:

3
