Purpose of new Boolean in JavaScript
The Boolean object represents two values, either "true" or "false". If value parameter is omitted or is 0, -0, null, false, NaN, undefined, or the empty string (""), the object has an initial value of false.
The new Boolean() is used to create a new object. Use the following syntax to create a boolean object.
var val = new Boolean(value);
Example
Let us see an example of toString() method, which returns a string of either "true" or "false" depending upon the value of the object −
<html> <head> <title>JavaScript toString() Method</title> </head> <body> <script> var flag = new Boolean(false); document.write( "flag.toString = " + flag.toString() ); </script> </body> </html>
