Boolean Object

  • In JavaScript, a boolean is a primitive data type that represents one of two values: true or false.
  • Booleans are typically used for making decisions and controlling the flow of a program. 

The boolean object is created by using the boolean constructor:

Boolean b=new Boolean(value);  
  • The default value is false.

Example:

<script>  
document.write(10<20);//true  
document.write(10<5);//false  
</script>
