Basic knowledge of Boolean objects in JavaScript programming

A Boolean (Boolean) object is used to convert a non-Boolean value to a Boolean value (True or false).

Checking Boolean values
Check whether the Boolean object is True or false.
Source code Example:

<! DOCTYPE html>
 
 

Test results:

0 is a Boolean false
1 is boolean true a
empty string is Boolean false
null are Boolean false
NaN is Boolean False the
string ' false ' is Boolean true

Create a Boolean object
a Boolean object represents two values: "True" or "false"
The following code defines a Boolean object named Myboolean:

var myboolean=new Boolean ();

If the Boolean object has no initial value or its value is:

0
-0
null
""
false
undefined
NaN

Then the value of the object is false. Otherwise, the value is true even when the argument is string "false"!
