Yeah I see just the feature of undefined behavior (in case you are familiar with this term) is a bad feature of those languages IMHO.

I think you missed the point that it's fashionable to rip on JS because you "should" be using TypeScript.

Tried the code in a new HTML page using Visual Studio 2017 and Google Chrome. The first alert showed "Apple Apple" and the second "Apple undefined". "Orange" did not show up.

Double check how the project is set up then. Here's a fiddle of it...

JSFiddle[^]

I tried JSFiddle and it worked. However, when I copied the exact code to a new HTML page, it behaved the same way as it was without "Orange". Here is the complete HTML code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title></title>
    <script type="text/javascript">

<pre>
    //copied from JSFiddle
    var fruit = 'Orange';
    window.fruit = 'Apple';

    // unlike other languages, in JavaScript we can invoke this in more ways than one
    function explainThis() {
        alert(fruit + ' ' + this.fruit);
    }

    explainThis(); // shows Orange Apple
    var stuff = new explainThis(); // shows Orange undefined
</script>

Gotcha. It's because stuff ran on JSFiddle is a mock root and not the real root. When using the real root, as in your case, window is the default object, so in the real global scope the first two lines are pretty much the same since window is the default object and so the second assignment overwrites the first. In my original code, it was a fake root so to speak. I probably should've tested it first, but hey where's the fun in that. Smile | :)

To illustrate...

HTML

<!DOCTYPE html>
<html lang="en">
<head>
   <script>
      // this is the real root in the global space
      var fruitRoot = 'Banana'; // these two lines do the same thing
      window.fruitRoot = 'Pineapple'; // this overwrites the previous line

      function explainThisRoot() {
         alert(fruitRoot + ' ' + this.fruitRoot);
      }

      explainThisRoot(); // shows Pineapple Pineapple
      var stuffRoot = new explainThisRoot(); // shows Pineapple undefined

      // this is an IIFE, simply put it's like a namespace
      (function () {
         // this can be thought of as a fake root, JSFiddle will do something similar to
         // constrain the user and prevent them from messing around with the entire page

         var fruit = 'Orange'; // not in the global space anymore so this isn't window
         window.fruit = 'Apple';

         // unlike other languages, in JavaScript we can invoke this in more ways than one
         function explainThis() {
            alert(fruit + ' ' + this.fruit);
         }

         explainThis(); // shows Orange Apple
         var stuff = new explainThis(); // shows Orange undefined
      })();
   </script>
</head>
<body>
</body>
</html>

And then the MORON who declares a variable like var window; which in one browser HIDES the window object, in the other it is ignored (a few years back).
And your code works in once place, and not the other! OMFG...

Otherwise, I actually LIKE javaScript as a teachable language. Just not the environment it lives!

I can see that. I would think that's my biggest qualm with it too, although I extend its environment to also mean the amount of people using it and everyone wanting to put their hand in the pie and make 40 million frameworks that aren't always designed well.

I never bother with bookmarks in the Chrome browser, because I organize my URL's of interest in a separate document.

But today, I wanted to bookmark the Jacquie Lawson Advent Calendar website my mother sent me. I realized I had absolutely no clue how to bookmark a page in Chrome. Had to google it. Oh, there's a "star" icon on the URL bar that I basically always ignore.

Now, how to find the bookmark. Ummm... Google again. Oh, the vertical ... and then "Bookmarks" But my bookmark isn't there. Another layer of indirection "Bookmark Manager" OK, still not there. Another layer of indirection (at this point I'm just clicking on things randomly) it's in the "Mobile bookmarks" folder.

WTF. I'm at home, on my laptop, not some mobile device. Gawd, these UI's suck Elephant | [mastadon]

there is a menu bar, on the menu bar is an item called Bookmarks. Oh wait, I'm using a good browser.

why do people use chrome?
apart from being a memory and CPU hog it's been so simplified (which makes that 'hog' thing even less rational) it needs a pack of add-ons to be remotely useful (which exacerbates the hog-ness). Perhaps the model they are using is soviet era cars? (Yes, those have a fan club too.)

In short: chrome sucks, it's not the fastest, it's far from the best.
(even ie has standard features chrome seriously needs).

I hate how Chrome doesn't scroll tabs, instead making them smaller and smaller as more are opened. The designer that created that (and whoever approved it) need to be taken out and shot.

Chrome also OOMs my system within 10 minutes, and I have 24 GB RAM! It will OOM even if it is the only program I've opened.

Try CTRL+SHIFT+B - it toggles a bookmarks bar just under the URL/google bar.
When you click the star, it remembers the last set you used and adds it to that, but you can change that with the "Folder" dropdown that appears when you click the star.
It makes sense when you are used to it, but they do have an annoying habit of swapping the "done" and "remove" buttons.

Quite so. I noticed the shortcut keys as I was traversing the menus. Then again, I'll probably forget them. Might already have. Wink | ;)
