- The lastIndexOf() method returns the position of the last occurrence of a specified value in a string.
- The string is searched from the end to the beginning, but returns the index starting at the beginning, at position 0.
- This method returns -1 if the value to search for never occurs.
- This method is case sensitive.
Code:-

<h1>lastIndexOf()</h1>
<input type="button" onclick="strfun();" value="Get Answer">
<script>
function strfun()
{
var str = "special News";
alert(str.lastIndexOf("s")); //Returns last matched character '11'
alert(str.lastIndexOf("f")); //'f' is not found in the given string, so it returns -1
