Creates a new Boolean value.
Syntax
boolObj = new Boolean([boolValue])
Parameters
boolObj
Required. The variable name to which the Boolean object is assigned.
boolValue
Optional. The initial Boolean value for the new object. If boolvalue is omitted, or is false, 0, null, NaN, or an empty string, the initial value of the Boolean object is false. Otherwise, the initial value is true.
Remarks
The Boolean object is a wrapper for the Boolean data type. JavaScript implicitly uses the Boolean object whenever a Boolean data type is converted to a Boolean object.
You rarely instantiate the Boolean object explicitly.
