JavaScript provides several methods to accomplish this, allowing you to clean up strings and ensure data integrity.

In this article, we will explore different approaches to removing whitespace from the start or end of a string. We will cover methods such as String.trim() , which is a built-in method specifically designed for this purpose, as well as using regular expressions with String.replace() . We will demonstrate an alternative approach also. By learning these techniques, you will be equipped to efficiently handle whitespace trimming in your JavaScript applications and ensure that your string data is properly formatted.
