Name
Boolean
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.
