Purely functional code makes some things easier to understand: because values don't change, you can call functions and know that only their return value matters—they don't change anything outside themselves. But this makes many real-world applications difficult: how do you write to a database, or to the screen? In this screencast we look at one method for crossing this divide.
Composition is a fundamental principle of functional programming, but how is it different from an object-oriented approach, and how do you use it in practice? In this talk for beginners, we'll start by going over the basic concepts of functional programming, and then look at some different ways that composition can be used to build large things from small things.
You could do this.. or you could do this... To avoid ambiguity I'll explain how I'm using a couple of terms in this article: • statement branching: any construct that alters the sequence of statement execution within the global or functional scope. These include if, else, switch, for and while statements. • micro-branching: conditional logic…
This dissertation introduces and elaborates the Representational State Transfer (REST) architectural style for distributed hypermedia systems, describing the software engineering principles guiding REST and the interaction constraints chosen to retain those principles, while contrasting them to the constraints of other architectural styles.
Two and a half hours of new beginner (free) and advanced React material are now available Egghead.io! I couldn’t be more excited to introduce you to what I can call my best work to date: Two new…
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
It’s been a while since I’ve been working with React — a Facebook library to build user interfaces using JavaScript — and there are a few concepts I wish I knew when I was just starting. This text is…
Angular (aka Angular 2, 4…) is a new framework completely rewritten from the ground up, replacing the now well-known AngularJS framework (aka Angular 1.x). More that just a framework, Angular should…
Stampit is a 1.3KB gzipped (or 2.7K minified) JavaScript module which supports three different kinds of prototypal inheritance (delegation, concatenation, and functional) to let you inherit behavior in a way that is much more powerful and flexible than any other Object Oriented Programming model.
How do we know how much Restful API is? Some developers call it “Not Restful API”, some call it “Partially Restful API”, for some, it is “Fully Restful API”, and for some “It is not REST API at all or they call it SOAP based web service”. Imagine it as a spectrum from Not Restful to Fully Restful API. To know at which level API stand, Richardson introduces a model called Richardson Maturity Model. As the name itself suggests, it tells about the maturity level of REST API.
This cookbook is targeting developers that already have a basic understanding of what React is and how it works. It's not meant to be used as a complete how-to guide but as an introduction to popular concepts/design patterns.
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.
The JavaScript language and ecosystem have seen dramatic changes in the last 2 years. In this sessions we'll look at patterns for organizing code using modul...
