The exception to this rule is if you are using untyped variables (i.e. `*`)
and need to test for `undefined` to the exclusion of `null`. In that case you
need `foo.baz === undefined`.
## Strings and Numbers
-Differences there
+Strings and numbers in Javascript can either be literal primitives (i.e.
`foo`, `3.14`) or classes (i.e. `new String("foo")`, `new Number(3.14)`). These
are two distinct types in Javascript and in turn in Typescript. In Typescript,
you would declare the former using `string` and `number`, while the latter
would be `String` and `Number`. Trying to mix the two in Typescript will cause
warnings.
+
+ActionScript does not differentiate between the two types. Both types use the
Uppercase notation, so you have `String` and `Number`, but no `string` or
`number` `'foo' is String` and `new String("foo") is String` both resolve to
true in ActionScript. If you try to use strict equality on the two (i.e.
`===`), it will fail, but if you use the standard ActionScript practices, you
don't need to worry about whether strings and numbers are literals or not.
