What is extra frustrating is that this is an answer StackOverflow. The whole point is to give clear, educational explanations. Well, the solution is only 21 lines, so why not explain the code snippet instead?

    (function() {
      function buggy() {
        function detect() {
          var a = [0, 1];
          a.reverse();
          return a[0] === 0;
        }
        return detect() || detect();
      }
      if(!buggy()) return;
      Array.prototype._reverse = Array.prototype.reverse;
      Array.prototype.reverse = function reverse() {
        if (Array.isArray(this)) this.length = this.length;
        return Array.prototype._reverse.call(this);
      }
      var nonenum = {enumerable: false};
      Object.defineProperties(Array.prototype, {
        _reverse: nonenum,
        reverse: nonenum,
      });
    })();

Look at how elaborate the repo is by comparison:

https://github.com/fanmingfei/array-reverse-ios12

It has a nice logo though I can't find a link to the merch store or author's Patreon.

? The snippet you showed is literally the exact code of the module: https://github.com/fanmingfei/array-reverse-ios12/blob/maste...

The rest is just tests / npm config / license

When I posted this, the snippet was not part of the answer being discussed. There was only a link to a node module.

You answered your own question. Especially in the JS world

I was so offended I raised an issue just to throw a strop: https://github.com/fanmingfei/array-reverse-ios12/issues/16

Also if now everyone starts to polyfill this garbage, then apple will not patch it before the next release of iOS.
