JavaScript's toString() method is used to convert any object into the string object. If we want to convert an object from one format into String format then it is very useful.
Syntax :
| object.toString(); |
Where object can be any object and this method will convert that object value to a string value. Let us understand use of toString() method with a very simple example. Here we have explained this by converting a Date object into the String object.
Description of code :
To illustrate toString() method , in this simple HTML page we have created a button and as soon as button is clicked convertToString() method is called which is defined in the JavaScript <script></script> tags.
| alert(new Date().toString()); |

Result of new Date().toString() method is a date converted into the string format and which is shown in an alert message box.
