ecma262 VS htmx

These aren't valid JavaScript (@@iterator would throw an error). They are actually internal Symbols used in JavaScript. They are used to implement features like iteration, instanceOf, and such internally. They actually might get removed or changed

Note that in previous editions, the ECMAScript® Language Specification used the term "lexical environment" before it decided to rename it to "Environment Record" so you might encounter this term in other definitions and tutorials.

For a new specification to be written, you need two things, a_ technical committee_, and a standard. The standard specification for JavaScript is called ECMA-262, and the technical committee is Technical Committee-39(TC39).

4. Proposed something else [ https://github.com/tc39/proposal-ptc-syntax ]

While apple is against Syntactic tail calls, they’re mainly just opposed to versions of it that would remove/unrequire the tail-call optimisation they already do: https://github.com/tc39/ecma262/issues/535

For the version of it that is backwards compatible, they wouldn’t need to do anything other than recognise it as valid syntax. Their main concern is that it "could add confusion with very little benefit."

The spec for STC has a critique of PTC:

- performance

- developer tools

- Error.stack

- cross-realm tail calls

- developer intent

See: https://github.com/tc39/proposal-ptc-syntax#issues-with-ptc

Apple's 2016 response as to why they won't implement STC is here: https://github.com/tc39/ecma262/issues/535

- STC is part of the spec and will take too long to change.

- Now that they've implemented support for PTC, they don't want to regress web pages that rely on it.

- They don't want to discourage vendors from implementing PTC by agreeing to STC.

- They don't want to introduce confusion.

Some of these arguments about confusion and delays seem wrong hindsight, since on every point things would have been better if they'd just agreed to the compromise of STC.

- It would have been part of the spec years ago

- STC would have had a clear way for web pages to know when tail calls could be relied on (and PTC would have been optional)

- Other vendors didn't implement PTC in any case, despite no agreement on STC

- There's even more confusion as things are now

When I work with HTMX I need isolated component that can be reusable a form. So I create a PHP Function that generate the Input Datalist.

I was inspired by htmz (which was in turn inspired by htmx) and how the author got pretty close to a basic htmx-like experience just using an iframe. I wanted to push it a little further so whipped this demo together. My submission demonstrates progressive enhancement for the form - with js enabled the request targets an iframe that is inserted into the dom, meaning the page doesn't actually navigate (similar to event.preventDefault()). The iframe receives the html response from the request and on load triggers a function to swap out it's contents into the main page.

As described on htmx.org: "htmx gives you access to AJAX, CSS Transitions, WebSockets and Server Sent Events directly in HTML, using attributes, so you can build modern user interfaces with the simplicity and power of hypertext"

Apart from the source code itself, the repo's README also gives a bit more details about the various packages I used.

Also, there’s some response header juggling you have to do when submitting forms that have a validation step before redirecting: https://github.com/bigskysoftware/htmx/issues/369

I’ve tried to iron out any footguns or server requirements I’ve bumped into while using HTMX & Hotwire in my projects.

✨ In recent months, I have been developing web projects using GOTTHA stack: Go + Templ + Tailwind CSS + htmx + Alpine.js. As soon as I'm ready to talk about all the subtleties and pitfalls, I'll post it on my social networks.

I've been digging into HTMX lately (using Python web frameworks) and find the concepts and approach to be interesting and promising. The idea of hypermedia driven systems over the current practice of JavaScript based frameworks (I never really got into React, played with Vue, and enjoy Svelte/SvelteKit) and the ability to chose your language/framework for the backend while primarily leveraging HTML/CSS on the frontend just seems refreshing.

Apparently it changed from 2-clause BSD: https://github.com/bigskysoftware/htmx/commit/e16f1865a494b6...

(The zero clause license drops the requirements for preserving the copyright notice when distributing)

It would be a sin not to start with something that prides itself on being the front-end library of peace. HTMX skyrocketed in popularity in 2023, gaining most of its GitHub stars during the past year. HTMX is not your average JS framework. If you work in HTMX, you will spend most of your time in the world of hypermedia, looking at web development from a completely different pair of eyes as compared to our usual JS-heavy outlook on modern web development. HTMX leverages the power of the concept of HATEOAS (Hypermedia as the Engine of Application State), enabling developers to access browser features directly from HTML, instead of using Javascript.
