What are JavaScript's builtin strings?

Question

this question is difficult to summarize in a question title

UPDATE I created a JSFiddle that builds an obfuscated string out of your input

Answer 1

This is about as close as I could get, unfortunately it violates the convention of the original obfuscation by making a call to unescape():

unescape((/%/+[])[1]+(/1/[1]+[])[1%1]+(+!1)+(+!1)+(1e1+(11*(1-~1)<<1)))

Teardown:

(/%/+[])[1]          => "%"
(/1/[1]+[])[1%1]     => "u"
(+!1)                => "0"
(+!1)                => "0"
(1e1+(11*(1-~1)<<1)) => "76"
===========================
unescape("%u0076")   => "v"

Other ideas:

1. Somehow get to unescape("\x76")
2. Somehow convert 118 without calling String.fromCharCode()
3. Get the text from an exception with the word "Invalid" in it

Updates:

I started playing code golf and have been making it shorter, replacing parts with more 1s, etc.
