🐛 bug report

I used https://github.com/TimTCrouch/WordList-JS in my app (which basically involves including https://github.com/TimTCrouch/WordList-JS/blob/master/src/wordList.js and https://github.com/TimTCrouch/WordList-JS/blob/master/src/wordBank.js in my index.html) and used “parcel build” to produce a bundle for browsers.

“parcel build” produced a wrong minified js for wordList.js with 2 issues:

• the global variable Word_List https://github.com/TimTCrouch/WordList-JS/blob/master/src/wordList.js#L10 was stripped
• the return statement https://github.com/TimTCrouch/WordList-JS/blob/master/src/wordList.js#L71 was stripped

After the 2 mentioned issues were manually fixed, my bundle worked. I reproduced the same error using the original https://github.com/TimTCrouch/WordList-JS/blob/master/testing.html instead of my index.html

🎛 Configuration (.babelrc, package.json, cli command)

The test setup I cloned https://github.com/TimTCrouch/WordList-JS to add my setup for using parcel here: https://github.com/minnie80/test-build-wordlistjs/blob/test-build-with-parcel/package.json

cli commands Build: npm run build Test: npm run prod

The test app http://localhost:3000/testing.html

🤔 Expected Behavior

The minified js in the bundle produced by “parcel build” should be correct. The corrected script:

var Word_List = (function () {
    var t = {},
      o = [];
    (t.isInList = function (t) {
      return o[(t = t.toLowerCase()).charAt(0)].indexOf(t) > -1;
    }),
      (t.getRandomWord = function (t) {
        0 == (t = t || 0) && (t = Math.floor(7 * Math.random()) + 4),
          t < 4 && (t = 4),
          t > 10 && (t = 10);
        var r,
          n,
          a = String.fromCharCode(Math.floor(26 * Math.random()) + 97);
        do (r = Math.floor(Math.random() * o[a].length)), (n = o[a][r]);
        while (n.length != t);
        return n;
      }),
      (t.loadBank = function (t) {
        var r = t[12].charAt(0);
        if (!r)
          throw "Not able to get first letter from word to determine word bank.";
        o[r] = t;
      });
      return t;
  })();

😯 Current Behavior

The incorrect script produced by “parcle build” (re-formatted by prettier.io):

!(function () {
  var t = {},
    o = [];
  (t.isInList = function (t) {
    return o[(t = t.toLowerCase()).charAt(0)].indexOf(t) > -1;
  }),
    (t.getRandomWord = function (t) {
      0 == (t = t || 0) && (t = Math.floor(7 * Math.random()) + 4),
        t < 4 && (t = 4),
        t > 10 && (t = 10);
      var r,
        n,
        a = String.fromCharCode(Math.floor(26 * Math.random()) + 97);
      do (r = Math.floor(Math.random() * o[a].length)), (n = o[a][r]);
      while (n.length != t);
      return n;
    }),
    (t.loadBank = function (t) {
      var r = t[12].charAt(0);
      if (!r)
        throw "Not able to get first letter from word to determine word bank.";
      o[r] = t;
    });
})();
