# JavaScript Boolean Object

The Boolean object is used to convert a non-Boolean value to a Boolean value (true or false).

## Examples

Check Boolean value
Check if a Boolean object is true or false.

## Complete Boolean Object Reference

For a complete reference of all the properties and methods that can be used with the Boolean object, go to our complete Boolean object reference.

The reference contains a brief description and examples of use for each property and method!

## Create a Boolean Object

The Boolean object represents two values: "true" or "false".

The following code creates a Boolean object called myBoolean:

    var myBoolean=new Boolean();

Note: If the Boolean object has no initial value or if it is 0, -0, null, "", false, undefined, or NaN, the object is set to false. Otherwise it is true (even with the string "false")!

All the following lines of code create Boolean objects with an initial value of false:

    var myBoolean=new Boolean();
    var myBoolean=new Boolean(0);
    var myBoolean=new Boolean(null);
    var myBoolean=new Boolean("");
    var myBoolean=new Boolean(false);
    var myBoolean=new Boolean(NaN);

And all the following lines of code create Boolean objects with an initial value of true:

    var myBoolean=new Boolean(true);
    var myBoolean=new Boolean("true");
    var myBoolean=new Boolean("false");
    var myBoolean=new Boolean("Richard");
