The documentation system outlined here is a simple, comprehensive and nearly universally-applicable scheme. It is proven in practice across a wide variety of fields and applications.
Cargo is the Rust package manager. Cargo downloads your Rust project’s dependencies, compiles your project, makes packages, and upload them to crates.io, the Rust community’s package registry.
If you inspect the source of a React Redux app, it could be overwhelming. But there is a method to the madness and it becomes very simple once you understand what’s going on. To understand it better…
Redux is becoming the de facto way to build React apps. And there are tons of examples that show how it’s done. But React-Redux apps have too many parts like: “Reducers”, “Actions”, “Action…
There was always some confusion around undefined in JavaScript. I’ll try to shed some light on it, and highlight why it might be better — i.e. safer and/or faster — to write void 0 in some cases…
JavaScript – love it or hate it, but it is still considered the “future” simply because it’s an essential language for web development. After all, browsers are probably the most-used software applications on computers and mobile devices alike.
Server side rendering a React app can provide a few different benefits including performance and SEO. The problem is with those benefits comes a cost of additional complexity to your application. In this post, we’ll start from scratch and slowly build a server side rendered React (with React Router) while breaking down some of the complexity as we go.
This site contains code repositories with documentation, and lots of resources. Logging, textFinder, blockingQueue, threadPool, comm, fileSystem, errorHandling, modelling and design patterns.
Rust for C programmers != Rust for functional programmers. … Although no current Rust manual dares putting it so bluntly, Rust is a functional language, inspired from recent advances in programming language design.
If reading multiple hundreds of pages about a language isn't your style, then Rust By Example has you covered. While the book talks about code with a lot of words, RBE shows off a bunch of code, and keeps the talking to a minimum. It also includes exercises!
Representational State Transfer (REST) has gained widespread acceptance across the Web as a simpler alternative to SOAP- and Web Services Description Language (WSDL)-based Web services. Key evidence of this shift in interface design is the adoption of REST by mainstream Web 2.0 service providers -- including Yahoo, Google, and Facebook -- who have deprecated or passed on SOAP and WSDL-based interfaces in favor of an easier-to-use, resource-oriented model to expose their services. In this article, Alex Rodriguez introduces you to the basic principles of REST.
Tim Griesser As JavaScript applications increase in complexity, consistent patterns for managing state becomes considerably more important, and difficult to ...
In this comprehensive tutorial, Dan Abramov - the creator of Redux - will teach you how to manage state in your React application with Redux. State management is absolutely critical in providing users with a well-crafted experience with minimal bugs. It's also one of the hardest aspects of a modern front-end application to get right. Redux provides a solid, stable and mature solution to managing state in your React application. Through a handful of small, useful patterns, Redux can transform your application from a total mess of confusing and scattered state, into a delightfully organized, easy to understand modern JavaScript powerhouse. The principles of Redux aren't new, but they are packaged and presented for you in an easy to use library that not only elevates your applications, but also improves your general understanding of building JavaScript UIs. In this course, Dan Abramov will show you the fundamentals of Redux, so that you can start using it to simplify your applications. There are some amazing community notes on this course here on Github. Once you are finished with this course be sure to check out part 2: building-react-applications-with-idiomatic-redux
Now don’t get me wrong, this doesn’t mean I can turn you into a React master instantly. But at least you’ll understand all the major concepts, if you do decide to jump in.
You should use this guide as a companion to the official Facebook documentation for getting started. While the official docs are great, the React ecosystem includes many other important projects which are outside the scope of the React docs.
This is the second part of our full-stack tutorial series that will walk you step by step through building an instant messaging app with React and GraphQL. Last week, in the first part of this…
When you build real world applications, you are not always on the "happy path". You must deal with validation, logging, network and service errors, and other annoyances. How do you manage all this within a functional paradigm, when you can't use exceptions, or do early returns, and when you have no stateful data?
The Python logging module comes with the standard library and provides basic logging features. By setting it up correctly, a log message can bring a lot of useful information about when and where the log is fired as well as the log context such as the running process/thread.
Understanding decorators is a milestone for any serious Python programmer. Here’s your step-by-step guide to how decorators can help you become a more efficient and productive Python developer.
This lesson shows what can be learned next as a continuation of this course, and gives a recap on the core concepts: main for pure logic, drivers for side effects, run() to connect main and drivers, sources for read effects, sinks for write effects, and nesting Cycle.js apps to work as components.
I’m an ancient web developer who is learning modern JavaScript. I’ve just gotten started and I’m having a ball, but I’ve also got whiplash. There are a few things I wish I’d understood and accepted about the world of modern JavaScript before I got started. Here are some of the changes I had to make to my own mindset and expectations around learning a new ecosystem based on an old language which has taken over my craft.
Learning modern JavaScript is tough if you haven’t been there since the beginning. The ecosystem is growing and changing so rapidly that it’s hard to understand the problems that different tools are…
Mithril.js is a small (7kb) and fast, classical MVC JavaScript framework. It encourages an architecture similar to Angular.js, and uses a virtual DOM like React.js, all while avoiding the need for libraries like jQuery. Mithril's small size and API makes it ideal for embedded JavaScript widgets and user interfaces that have high performance requirements.
I found middlewares both easy to understand and a useful addition to my Redux toolbox. And I think after reading the source code for the following 3 popular middlewares you'll feel that way too.
This book is targeted at professional developers wishing to improve their knowledge of design patterns and how they can be applied to the JavaScript programming language.

Maybe you’ve seen the syntax before, but why in the heck does an Immediately-Invoked Function Expression (IIFE — pronounced ‘iffy’) look like it does? Why is it useful?
Despite its popularity, few know that JavaScript is a very nice dynamic object-oriented general-purpose programming language. How can this be a secret? Why is this language so misunderstood?

The Symbol and Generator were added on ES2015 and they use is pretty blurry for some developers. So, in this article, I’ll try to simplify and explain it, then show some use cases.
One simple reason. JavaScript has two visually similar, yet very different, ways of testing equality. This is your high level overview of the differences.
Following the original JavaScript hacks for hipsters, here’s some new goodies. Coding JavaScript in 2018 is actually fun again! Once again, Array Destructuring is great. Combined with async/await and…
Unlike most introductions to JavaScript, these lessons present an even mix of browser programming and server programming. We give each topic only shallow coverage; if you want to know more, there are many other free tutorials you can dive into once you’ve mastered the basics, some of which are both up-to-date and well designed.
JavaScript Allongé is a first and foremost, a book about programming with functions. It’s written in JavaScript, because JavaScript hits the perfect sweet spot of being both widely used, and of having proper first-class functions with lexical scope.
