trimRight

trimRight is a common programming function used to remove trailing whitespace characters or specified characters from the end of a string. It is often utilized to clean up user input, process data, or prepare strings for further manipulation by ensuring there are no unwanted characters at the end.

The primary purpose of trimRight is to eliminate whitespace such as spaces, tabs, or newline characters that may inadvertently be present after meaningful content. Many programming languages or libraries implement functions similar to trimRight under different names, such as rtrim in PHP, rightTrim, or trimEnd in JavaScript.

In JavaScript, for example, the method trimEnd() performs a similar operation, removing whitespace characters from the end of a string. The traditional trimRight() method has been deprecated in favor of trimEnd(), but both serve the same purpose.

Sample usage of a trimRight function could involve removing trailing spaces from a string: given the string "Hello, World! ", applying trimRight would result in "Hello, World!".

Custom implementations of trimRight can often be adapted to remove specific characters other than whitespace by passing those characters as parameters. This flexibility makes the function a valuable tool in string processing tasks across various programming contexts.

Overall, trimRight or its equivalents are standard utility functions in many programming languages aimed at simplifying string sanitization and manipulation.
