Deobfuscating Obfuscator io is no longer working

To Reproduce
it does not work anymore for obfuscator io
i tried with the obfuscator io sample

// Paste your JavaScript code here
function hi() {
  console.log("Hello World!");
}
hi();

-> obfuscated:

var _0x305e=['9saDTIV','326PQEvGs','56489vfJpQr','log','316680vTtHaV','167leqdwt','Hello\x20World!','92112VNXwdf','135890nrPiXD','175642lixkia','594079wXNZKt'];var _0x2a47=function(_0x816949,_0x40e825){_0x816949=_0x816949-0x152;var _0x305eb0=_0x305e[_0x816949];return _0x305eb0;};(function(_0x3700ba,_0x18dfd4){var _0x2e4789=_0x2a47;while(!![]){try{var _0x5919da=parseInt(_0x2e4789(0x154))+-parseInt(_0x2e4789(0x155))+parseInt(_0x2e4789(0x15c))+parseInt(_0x2e4789(0x156))+parseInt(_0x2e4789(0x15a))*parseInt(_0x2e4789(0x158))+parseInt(_0x2e4789(0x152))*-parseInt(_0x2e4789(0x159))+-parseInt(_0x2e4789(0x157));if(_0x5919da===_0x18dfd4)break;else _0x3700ba['push'](_0x3700ba['shift']());}catch(_0x226ab0){_0x3700ba['push'](_0x3700ba['shift']());}}}(_0x305e,0x4b4c8));function hi(){var _0x3c243f=_0x2a47;console[_0x3c243f(0x15b)](_0x3c243f(0x153));}hi();

but when trying to deobfuscate, in the console i have the error

Decode Error! ErrorEvent {isTrusted: true, message: "Uncaught Error: Not matched", filename: "http://127.0.0.1:4000/de4js/worker/decode.js", lineno: 79, colno: 11, …}

Same #59 but more detail 👍

Code obfuscated from obfuscator.io will not work with the following options:

• Eval
• Array
• Obfuscator io
• _Number
• JSFuck
• JJencode
• AAencode
• URLencode
• Packer
• JS Obfuscator
• My Obfuscate

I don't know if some of these are intended to throw javascript errors or not. But they all throw different errors usually "Not Matched" though. Just some more info on this bug.

No hope - at this time.

@lelinhtinh Why no hope at this time? Do you want a PR?

I've managed to write a deobfuscator that works on obfuscator.io using jscodeshift and could probably port (i.e. rewrite from scratch) the relevant code to whatever framework this tool is based on.

[lelinhtinh]

PR is always welcome. However, you should consider specialized projects, and the code is cleaner.

Ah, thanks! I've missed those projects.
What was the major barrier for supporting the latest updates of obfuscator.io in this project?
