Typed Wrappers
JavaScript has a set of typed wrappers. For example:
new Boolean(false)
produces an object that has a valueOf method
that returns the wrapped value. This turns out to be completely unnecessary and
occasionally confusing. Don't use new Boolean or
new Number or new
String.
Also avoid new Object and new Array. Use {}
and [] instead.
