how to remove the last word in the string using JavaScript
<p>I would like to know how can I remove the last word in the string using JavaScript?</p>

<p>For example, the string is "I want to remove the last word."</p>

<p>After using removal, the string in the textbox will display "I want to remove the last"</p>

<p>I've seen how to remove the last character using the  substring function, but because the last word can be different every time. Is there a way to count how many word is required to remove in JavaScript?</p>

<p>Thanks</p>
