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>
