Episode 24/13: Native Signals, Details on Angular/Wiz, Alan Agius on the Angular CLI
Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

What We Need Instead of "Web Components"
> This proposal makes the same mistake as various stream implementations (including RxJS in the past) of making operators methods on the observable.
I don't think they are making a mistake. I am sure Ben knows what he is doing, given how it was he who refactored rxjs 5 with all operators being methods on the Observable, to rxjs 6 with pipeable operators.
But, their objective is not to bring rxjs into the browser, but rather to bring the Observable primitive into the browser. And, like Array prototype, which has methods, Observable, in order to be even minimally useful, needs some methods, which they modelled from TC39 iterators, for the sake of consistency.
They say:
> We expect userland libraries to provide more niche operators that integrate with the Observable API central to this proposal, potentially shipping natively if they get enough momentum to graduate to the platform. But for this initial proposal, we'd like to restrict the set of operators to those that follow the precedent stated above, similar to how web platform APIs that are declared Setlike and Maplike have native properties inspired by TC39's Map and Set objects. Therefore we'd consider most discussion of expanding this set as out-of-scope for the initial proposal, suitable for discussion in an appendix. Any long tail of operators could conceivably follow along if there is support for the native Observable API presented in this explainer.
As to
> We really need a `pipe` operator, at minimum
Maybe we don't. Note that in RxJS version 8, they have introduced a new way of piping observables, which is the rx function [0]. Maybe they are thinking of something similar for the browser. Or maybe they are thinking of using the native pipeline operator if it ever gets approved.
In the meantime, for any complex manipulations on observables, users will probably still import relevant functions from libraries.

Want to raise the bar 💯
Hello and welcome! It's fantastic that you're looking to broaden your expertise in front-end development. Transitioning from Flutter to React and Angular is a great move, as it will provide you with a well-rounded skill set. ### Resources for Learning React: 1. **Official Documentation:** Start with the [official React documentation](https://reactjs.org/). It's well-written and comprehensive. 2. **React Fundamentals Courses:** Platforms like [freeCodeCamp](https://www.freecodecamp.org/) and [Codecademy](https://www.codecademy.com/) offer free React courses. 3. **React Hooks:** Understand the concept of hooks, a powerful feature in React. The [React Hooks documentation](https://reactjs.org/docs/hooks-intro.html) is a great resource. 4. **Project-Based Learning:** Build small projects to apply your knowledge. You can find ideas on platforms like [GitHub](https://github.com/) or [CodePen](https://codepen.io/). 5. **React Router:** Learn how to handle navigation in React using [React Router](https://reactrouter.com/). ### Resources for Learning Angular: 1. **Official Documentation:** Similar to React, start with the [official Angular documentation](https://angular.io/). 2. **Angular Tour of Heroes:** This is a hands-on tutorial provided in the Angular documentation. It's an excellent resource for getting started. 3. **Angular University:** [Angular University](https://angular-university.io/) offers comprehensive courses on Angular. 4. **RxJS:** Learn about reactive programming using RxJS, which is heavily used in Angular. You can find resources on the [official RxJS documentation](https://rxjs.dev/). 5. **Build Real-World Apps:** Build practical applications to solidify your understanding. The more you code, the better you'll become. ### Making a Mark in the Open-Source Front-End Space: 1. **GitHub Contributions:** Contribute to existing open-source projects. This not only helps you learn but also establishes your presence in the community. 2. **Create Your Projects:** Start small with your open-source projects. Share them on GitHub, and seek feedback from the community. 3. **Participate in Hackathons:** Join online hackathons or coding challenges. They're great for learning and networking. 4. **Follow Blogs and Newsletters:** Stay updated with the latest trends and best practices in the front-end world. Subscribe to newsletters like [JavaScript Weekly](https://javascriptweekly.com/) or [React Status](https://react.statuscode.com/). 5. **Join Forums and Communities:** Engage with developers on platforms like [Stack Overflow](https://stackoverflow.com/) or specialized forums for React and Angular. Remember, the key is consistent practice and learning by doing. Good luck on your journey, and feel free to reach out if you have more questions! 🚀

Web scraping LinkedIn jobs using Puppeteer and RxJS
Web scraping may seem like a simple task, but there are many challenges to overcome. In this blog, we will dive into how to scrape LinkedIn to extract job listings. To do this, we will use Puppeteer and RxJS. The goal is to achieve web scraping in a declarative, modular, and scalable manner.

This is the standard way of going about things in Mithril and Cycle. Elm as well doesn't use an XML knockoff for view code- and as a fun fact, the original version of React didn't either.

Does it make sense to use Scala.js/Laminar in the context of a startup?
TypeScript is relatively mainstream at this point, and I think that's good news. If you want to crank the type-safety and pure FP dials on it to 11, you certainly can do that. I have a project that I've based largely on this post, including the "hardcore" section. However, instead of Redux and otherwise plain React, I've chosen to use Cycle.js and the lessons from this post to use React in a very purely Functional Reactive Programming Way.

Flame: A PureScript front-end framework inspired by the Elm architecture
This post links to a PureScript project that is probably the easiest PS framework around.
ReScript + rescript-react is a good alternative. Less safe, waaaay more verbose; but backed by Facebook.
This is quite cute (in TypeScript though): https://github.com/cyclejs/cyclejs
And Yew is super cool, it goes the WASM route (in Rust): https://github.com/yewstack/yew

My Open Source Journey
From now on I was on what I would call a typical open source trajectory. I used the Cycle.js framework to rewrite my frontend and in that process I hit some walls. I eventually figured that the error was on my side and that I was just missing some information to avoid the error. To spare others the hours of debugging I started to contribute small patches to the documentation. At the same time I also found some missing features that I voiced in GitHub issues.
What are some alternatives?

MobX - Simple, scalable state management.
Bacon - Functional reactive programming library for TypeScript and JavaScript
kefir - A Reactive Programming library for JavaScript
Cycle.js (react-native) - Cycle.js driver that uses React Native to render
