In previous example, we saw how JavaScript treat string as an array and allow us to access its character using indexOf() method.
But sometimes, there are more than one occurrence of a character in the string. To know the index of last occurrence of a string. JavaScript has <span style="color:#a30500" class="tadv-color">lastIndexOf()</span> method in the string class.
Here is an example of the method – lastIndexOf().
<!DOCTYPE html>
<html>
<head>
<title>JS: lastIndexOf() Method</title>
<meta charset="utf-8">
</head>
<body>
<script>
var animal = "elephant";
var out = animal.lastIndexOf('e');
console.log(out);
//outputs = 2
</script>
</body>
</html>In the above example, there are two occurrence of character ‘e’. The <span style="color:#a30000" class="tadv-color">lastIndexOf()</span> method returns the index value of last occurrence of ‘e’ which is 2.
