"receiver" is indeed a bit of a misnomer for the apply trap. "thisArg" is
more sensible. I'll update the wiki page.
You probably missed it, but the role of the "thisArg"/"receiver" parameter
is described by example using the following code snippets on the direct
proxies wiki page:
proxy(...args); // triggers handler.apply(fun, undefined, args)
var obj = { m: proxy }; obj.m(...args); // triggers handler.apply(fun, obj,
args)
Function.prototype.apply.call(proxy, rcvr, args); // triggers
handler.apply(fun,rcvr,args)
Cheers,
