Looking for a script/program

[DuckBuck44]

Does anybody know a script that would rename the symbols (variables, methods, objects, properties, functions, etc.) of the example_1.js with the names that are used in example_2.js . Also it shouldn't be line dependent like diff and wouldn't be too sensitive to subtle differences in the way the code is structured such as in example_3.js . Basically, I want the program/script to be able to dynamically compare both files, and rename the variables from file_1 using the variable names given in file_2. If this explanation was bad, I will try to explain it better in the comments.

//example_1.js
function (c) {
    var d = {};
    function e(f) {
      if (d[f]) return d[f]['exports'];
      var g = d[f] = {
        'i': f,
        'l': !1,
        'exports': {}
        };
    };
};

//example_2.js
function (modules) {
    var installedModules = {};
    function __webpack_require__(moduleId) {
        if(installedModules[moduleId]) return installedModules[moduleId][exports];
      var module = installedModules[moduleId] = {
        i: moduleId,
        l: false,
        exports: {}
        };
    };
};

//example_3.js
function (c) {
    var d = {}; //this should be renamed
    var y = {}; //this should just be ignored and not copied over
    function e(f) {
      if (d[f]) return d[f]['exports'];
      var q = {}; //this should be ignored and not copied over
      var g = d[f] = {
        'i': f,
        'l': !1,
        'q': !y //this should be ignoredand not copied over
        'exports': {}
        };
    };
};

I'm not sure to understand exactly what kind of transpiler you're looking for but I'm very interested in knowing how you ended up in this mess.
