StringprototypetrimEnd

StringprototypetrimEnd is a JavaScript method that removes whitespace from the end of a string. It does not modify the original string but returns a new string with the trailing whitespace removed. Whitespace characters include spaces, tabs, and line terminators. This method is a part of the ECMAScript 2019 specification and is widely supported in modern browsers.

To use StringprototypetrimEnd, you call it directly on a string variable. For example, if you have a string named myString, you would write myString.trimEnd(). The method accepts no arguments.

Consider a string with trailing spaces: " Hello World ". Calling trimEnd() on this string would result in " Hello World". The whitespace at the beginning of the string remains untouched.

This method is useful for cleaning up user input or data retrieved from external sources where trailing whitespace might be present and could cause issues in comparisons or display. It is a counterpart to StringprototypetrimStart, which removes whitespace from the beginning of a string, and Stringprototypetrim, which removes whitespace from both ends.
