The manual contains a detailed description of each property and method, as well as related examples.
Create a Boolean object
The 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, its value is true (even when the variable value is the string "false")!
