JavaScript ToString Function Example

The following set of examples will help you understand the ToString function in JavaScript Programming Language.

TIP: The ToString function does not accept any arguments.

<!DOCTYPE html>

<head>
    <title> ToString JavaScript </title>
</head>
<body>
    <h1> JavaScript ToString </h1>

    var Str3 = 4567;
    var Str4 = Str1.toString();
    var Str5 = Str2.toString();
    var Str6 = Str3.toString();
    
    document.write(Str4 + "<br \>");
    document.write(Str5 + "<br \>");
    document.write(Str6 + "<br \>");
    document.write(typeof(Str5) + "<br \>");
    document.write(typeof(Str6) );
</script>
</body>
</html>

OUTPUT

JavaScript TOSTRING Function

ANALYSIS

First we declared three String variables Str1, Str2, Str3 and assigned corresponding values using following statement

  var Str1 = "Tutorial Gateway"; //String
  var Str2 = 123.45; //Float
  var Str3 = 4567; //Integer

The following JavaScript statements will convert the decimal and integer values to string values

  var Str4 = Str1.toString();
  var Str5 = Str2.toString();
  var Str6 = Str3.toString();

Next, We used the TypeOf Function, to show you the Data type of the variable. From the above screenshot, you can observe that the data type of Str2 (decimal) and Str3 (integer) converted to string type.

 document.write(typeof(Str5) + "<br \>");
 document.write(typeof(Str6) );

JS toString Function Example 2

Here, we are using this tostring function to convert today’s date and time to a string object.

<!DOCTYPE html>
<html>
<head>
    <title> JavaScript Date toString Function  </title>
</head>
<body>
    <h1> JavaScript toString Example </h1>
<script>
  var dt = Date();  
  document.write("Date and Time : " + dt + "<br/>");

  var x = dt.toString();
  document.write("After toString() = " + x);
</script>
</body>
</html>

OUTPUT

JavaScript toString Function 1
