A (incomplete) deobfuscator for scripts obfuscated with obfuscator.io, feel free to use it.
I may add more features or clean the code up at some point.
obfuscator.io have added some new features and while still pretty trivial to reverse I do not plan on updating this repository.

Deobfuscated script
function a() {
var c = {};
c.CKtQa = 'Hello World!';
var d = c;
console.log(d.CKtQa);
}
a();
Put the obfuscated script in source/obfuscated.js and run:
npm start
