Nice explanation! However, I'm not happy with the last line of your last code example:

button.addEventListener('click', () => span.innerHTML = ++numberOfPresses);
Enter fullscreen mode Exit fullscreen mode

The occurrence of both => and = make the expression somehow difficult to read.

One could use parentheses to emphasize the assignment:

button.addEventListener('click', () => (span.innerHTML = ++numberOfPresses));
Enter fullscreen mode Exit fullscreen mode

Or maybe one could spend a new line:

button.addEventListener('click',
  () => (span.innerHTML = ++numberOfPresses)
);
Enter fullscreen mode Exit fullscreen mode

I totally agree with you there. I don't have the best code formatting skills, so that's nice of you to bring up. I'll go edit the format right now. Thanks for the suggestion!

I suggest using prettier, since it is have become a well accepted and easily readable code format.

You can try it out here:

As nice as a standardized code format sounds, I just can't agree with some of them. I'm looking at you, "Standard" JS. I prefer to have my own coding style. I think of coding as an "art form", where my coding style is my "signature".

Don't let that discourage you from using Prettier, though. I totally agree with its objective to standardize code formats for the sake of productivity and readability.

Oh man, I also despited Standard when I first tried it! What a frustrating experience I.

For some reason though, my experience with prettier has been almost the opposite. I think it's partly due to it having sane and very readable defaults and partly because I've set it up to match my personal code style (e.g. no semi-colons).

I've discovered how having automatic formatting in my editor is priceless for productivity! No more fiddling with indents and line breaks. Recently I've found myself using Format On Save in Visual Studio Code more often, as it just makes having clean code that much easier.

To me, I primarily disagreed with how Standard JS treats semicolons. I mean just look at this absurdity! I don't like how it is being too clever with the format.

;[1, 2, 3].forEach(bar)
;(function () {
  window.alert('ok')
}())
;`hello`.indexOf('o')

Of course, this is an extreme example. Even their documentation discourages lines of code that begin with [, (, and the like. Nonetheless, I just feel strange when they have the audacity to call it "Standard" JS in the face of some weird syntax that is too clever.
