Example 2

The following is another example of the JavaScript String toString() method. Here, we invoke this method on a reference variable of a String object to retrieve the value of the object. As we discussed, this method is automatically called when a String object is used (created), but if you print the reference variable value in the console, it will display as String {"value"}.

<html>
<head>
<title>JavaScript String toString() Method</title>
</head>
<body>
<script>
   const strObj = new String("Hello World");
   console.log("The strObj value: ", strObj);
   // it will print String{"Hello World"};
   document.write("The strObj.toString() method returns: ", strObj.toString());
   // it will print "Hello World";
</script>    
</body>
</html>

Output

After executing the above program, it will return "Hello World".

The strObj.toString() method returns: Hello World
