This patch adds instance, constructor and prototype classes for:
- EvalError
- InternalError
- RangeError
- ReferenceError
- SyntaxError
- TypeError
- URIError
Enumerator macros are used to reduce the amount of typing. :^)
We already have "global" as a way to access the global object in js(1)
(both REPL and script mode). This replaces it with "globalThis", which
is available in all environments, not just js.
There is no such thing as a "undefined literal" in JS - undefined is
just a property on the global object with a value of undefined.
This is pretty similar to NaN.
var undefined = "foo"; is a perfectly fine AssignmentExpression :^)
This adds:
- A global Date object (with `length` property and `now` function)
- The Date constructor (no arguments yet)
- The Date prototype (with `get*` functions)
Instead of implementing every native function as a lambda function,
use static member functions instead.
This makes it easier to navigate the code + backtraces look nicer. :^)
Native functions now only get the Interpreter& as an argument. They can
then extract |this| along with any indexed arguments it wants from it.
This forces functions that want |this| to actually deal with calling
interpreter.this_value().to_object(), and dealing with the possibility
of a non-object |this|.
This is still not great but let's keep massaging it forward.
