Answer 1

Following answer by Amir Raminfar, I found this solution. In my opinion, it's better than accepted answer, because it works even if you have a space at the end of the string or with languages (like French) that have spaces between last word and punctuation mark.

"Je veux supprimer le dernier    mot !".replace(/[\W]*\S+[\W]*$/, '')
"Je veux supprimer le dernier"

It strips also the space(s) and punctuation marks before the last word, as the OP implicitly required.

Peace.

Answer 2

If anyone else here is trying to split a string name in to last name and first name, please make sure to handle the case in which the name has only word.

let recipientName = _.get(response, 'shipping_address.recipient_name'); let lastWordIndex = recipientName.lastIndexOf(" "); let firstName = (lastWordIndex == -1) ? recipientName : recipientName.substring(0, lastWordIndex); let lastName = (lastWordIndex == -1) ? '' : recipientName.substring(lastWordIndex + 1);

Answer 3

You can do a simple regular expression like so:

"I want to remove the last word.".replace(/\w+[.!?]?$/, '')
>>> "I want to remove the last"

Finding the last index for " " is probably faster though. This is just less code.
