Function:
number
number(object)
The top-level function, number, converts the object
argument to a string representing the object's value. If the value cannot
be represented by a legitimate number, the "Not-a-Number" value, NaN
is returned.
The object argument must be a JavaScript object. If no argument
is provided, number returns zero, 0.
In this example, a new Boolean object is created with a string
argument of "true". The number function returns, 1, which is
the number equivalence of the value of the object.
Code:
boo = new Boolean("true")
document.write(Number(boo))
Output:
1
