Signals, Signals: But What Can I Do With Them In My Laboratory?

I just went to svelte’s website, and copied their two most fanciful examples.

Updating a numeric value, at the click of a button.

And updating webpage text, based on an input box.

And the little signals library that I programmed for this text, was able to handle both much better than svelte.

And svelte is the nicest HTML framework, even with the ruinous runes that they just added.

Out little signal library, shamed a massive framework.

Including Rx, which my operator names are based on.

I’ve put very little effort into it, everything is like 3 lines of code in size.


This tells me that signals, are a force of nature.

They are the future, HTML extends JavaScript, and signals extend HTML making it reactive.

As you can see in the attached code, remember to click view source on the HTML demo page.

They maybe the best starting point for learning JavaScript and HTML programming.

It is the noblest code, and most respectful, as it is both simple and profoundly enabling at every line.

Print out this code, and pace with it, take it with you everywhere you go.

Turn all your waiting, walking and exercising, into learning, and getting goosebumps, and getting mad at High School.


I left some unfinished operators, but you should never feel that you have enough of them.

And as you can see with setInnerTextOf, add you own, especially on per program basis.


Your custom operators, become the core of the vocabulary of your application.


Reactive programming is a natural extension of JavaScript, but you can’t hope to learn it by looking at lists of operators.

You start with a Pulse, or a Signal, and then you add .map, .filter, .combineLatest.

And signal creation functions like fromEvent, where you tap into HTML elements.

Be it keyup of an input box, or click of a button.

From here, operators come to you naturally, what else could you do or need when from event five you user interface data.

You just combine it, map it, and subscribe to the result.

That you can then send to server as action, or database as record.

Public AI understand it well, it will give you 99.5% correct response.
