A JavaScript Boolean object can represent two values “true” or “false”.
How to create a Javascript boolean object:
1. By using boolean literals.
2. By using Boolean() constructor.
Syntax:
Var b1 = true; var b2 = new Boolean(value);
Example:
<!DOCTYPE html> <html> <body> <script> var boolean1=new Boolean(true); var boolean2=new Boolean(false); var boolean3=true; document.write("Boolean1: "+boolean1+ "</br>"); document.write("Boolean2: "+boolean2+ "</br>"); document.write("Boolean3: "+boolean3); </script> </body> </html>
