Some things that are "better" with this BetterPromise implementation:

• BetterPromise # then(..) accepts a BetterPromise (or Promise) instance passed directly, instead of requiring a function to return it, so that the promise is linked into the chain.

  var p = BetterPromise.resolve(42);
  
  var q = Promise.resolve(10);
  
  p.then(console.log).then(q).then(console.log);

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

• charAt(pos: number): string ^ES1

  Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Mobile Safari does not support position: fixed when an input focused and virtual keyboard displayed.

To force it work the same way as Mobile Chrome, you have to use position: absolute, height: 100% for the whole page or a container for your pseudo-fixed elements, intercept scroll, touchend, focus, and blur events.

The trick is to put the tapped input control to the bottom of screen before it activates focus. In that case iOS Safari always scrolls viewport predictably and window.innerHeight becomes exactly visible height.

Open https://avesus.github.io/docs/ios-keep-fixed-on-input-focus.html in Mobile Safari to see how it works.

Please avoid forms where you have several focusable elements because more tricks to fix position will be necessary, those were added just for demonstration purposes.

As you start out with your Electron app, you'll start to notice some features which have been carried directly across from the browser realm but make less sense for a desktop app. Here are the ones I can remember:

Ctrl or ⌘ + Click Opens Links in New Window

In Electron just like in Chrome, if you hold down the Ctrl key (or ⌘ on Mac) while clicking a link it opens in a new window. For many SPA apps, this is undesired and will load another full copy of your app in another window. You can disable this by calling the following code once you've created a BrowserWindow

win = new BrowserWindow({ ... });
