| Boolean |
Core JavaScript 1.1; JScript 2.0; ECMA v1 |
| a wrapper object for boolean values |
|
Constructor
new Boolean(value)
Boolean(value)
Invoked as a function, without the new operator,
Boolean( ) converts
value to a boolean value (not a Boolean
object) and returns it. All values convert to true
except for 0, NaN, null,
undefined, and the empty string,
"". When invoked with the
new operator, the Boolean( )
constructor performs the same conversion and wraps the result in a
Boolean object.
Methods
- toString( )
-
Returns "true" or
"false", depending on the value of
the Boolean object.
- valueOf( )
-
Returns the primitive boolean value wrapped by the Boolean object.
