How to Use the LPAD Function in JavaScript?

In JavaScript, you can use the padStart() method to achieve the same functionality as the LPAD function in other programming languages. The padStart() method allows you to add padding (specified by a string) to the beginning of a string, until it reaches a specified length. Here’s an example of how you could use it:

let originalString = '1234';
let paddedString = originalString.padStart(10, '0');
console.log(paddedString);

This will output:

000000001234

In this example, the originalString is padded with 0s until its length reaches 10.
