I have a js file with no external dependencies. It has two parts, one looking like this:

 {
        b: "IxIjACMBQzM=",
        U: [0],
        G: [0],
        k: [1, 18]
    }, {
        b: "IxFMTgH+EAH/J0sfQyQCIwIvAAFJAC1MTgH+EAH/JztOAcsnIwEeAS8BGTM9IwIz",
        r: 0,
        U: [1],
        G: [1, 2],
        k: [17, 18]
    }, {
        b: "IwE7TgIPEAJDJyMAIwMeAgwg",
        U: [0],
        G: [0],
        k: [1, 3]
    },

And then there are the numerous functions that look like this:

 function(fp) {
      var fq = fp.T.Y();
      var fr = fp.T.Y();
      fp.T.x(fr instanceof fq)
    }
...
    function gw(gx, gy) {
      "use strict";
      var gz = gr.Z[gx];
      return gA(gz.I, gy, gz.G, gz.k, gz.U, gz.S, gz.r)
    }

When executed, the script creates a real function (let's say hello()) that contains a base64 string. I would like to get to the logic behind hello(), to see how it generates the string, but I have no idea where to start. Any help would be appreciated.

  • I think is is impossible to answer without seeing the full script. – w s Feb 4 at 10:40
  • @ws what about getting the “bytecode” of the already defined function “hello()”. Does such thing exist in the javascript context? – technology Feb 4 at 18:06
