undefined compiles in to nothing

[takashi1kun]

i have a script that basically checks

someVariable === undefined && etc...

When i convert it to jsfuck and run it and then the browser it gives error because it is read as:
someVariable === && etc...

You can check by compiling this code:

if(undefined == undefined && true){console.log("test")}

It gives error Unexpected token '==' and if you click the VM in the debug console to see what is doing it appears it gets compiled to this:

(function anonymous(
) {
if( ==  && true){console.log("lol")}
})

Same as #68 (fixed in #75)

I assume you are talking about the website, which has outdated version.
