What is an acceptable way to remove a particular trailing character from a string?
For example if I had a string:
> "item," And I wanted to remove trailing ','s only if they were ','s?
Thanks!

To remove leading and trailing spaces in Java, use the trim() method. This method returns a copy of this string with leading and trailing white space removed, or this string if it has no leading or trailing white space.
To remove the last character from a string in JavaScript, you should use the slice() method. It takes two arguments: the start index and the end index. slice() supports negative indexing, which means that slice(0, -1) is equivalent to slice(0, str. length - 1) .
JavaScript provides three functions for performing various types of string trimming. The first, trimLeft() , strips characters from the beginning of the string. The second, trimRight() , removes characters from the end of the string. The final function, trim() , removes characters from both ends.
Use a simple regular expression:
var s = "item,"; s = s.replace(/,+$/, ""); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
