ES6 brought a number of new features to the JavaScript language. Two of these features, generators and iterators, have substantially changed how we write specific functions in more complex front-end code. While they do play nicely with each other, what they actually do can be a little confusing, so let’s check them o...
In the first part of this miniseries, we started digging into the world of React to see how we could use it, together with Node.js, to build a React Universal Blog App. In this second and last part, we’ll take our blog to the next level by learning how to add and edit content. We’ll also get into the real m...
When the topic of single page applications (SPAs) comes up, we tend to think of browsers, JavaScript, speed, and invisibility to search engines. This is because an SPA renders a page’s content using JavaScript, and since web crawlers don’t use a browser to view web pages, they can’t view and index the...
While ES2015 has introduced many language features that have been on developers’ wish lists for some time, there are some new features that are less well known and understood, and the benefits of which are much less clear — such as symbols. The symbol is a new primitive type, a unique token that’s guaranteed neve...
Often we need to represent an idea or concept in our programs — maybe a car engine, a computer file, a router, or a temperature reading. Representing these concepts directly in code comes in two parts: data to represent the state, and functions to represent the behavior. ES6 classes give us a convenient syntax for de...
In computing terms, proxies sit between you and the things you’re communicating with. The term is most often applied to a proxy server — a device between the web browser (Chrome, Firefox, Safari, Edge etc.) and the web server (Apache, Nginx, IIS etc.) where a page is located. The proxy server can modify requests an...
Destructuring assignment sounds complex. It reminds me of object-oriented terms such as encapsulation and polymorphism. I’m convinced they were chosen to make simple concepts appear more sophisticated! In essence, ECMAScript 6 (ES2015) destructuring assignment allows you to extract individual items from arrays or obj...
ECMAScript 6 (a.k.a. ECMAScript 2015 or ES6) brings a number of new features to JavaScript which will make the language a good fit for large applications. One of these features is better support for asynchronous programming using promises and generators. Another is the addition of the Fetch API which aims to replace XM...
This article is part of a web development series from Microsoft. Thank you for supporting the partners who make SitePoint possible. Since releasing babylon.js, the WebGL open-source gaming framework, a couple of years ago, we (with help from the community) are constantly exploring ways to make it even better. I’m def...
ECMAScript6 or ES6 is the evolution of JavaScript and it is the future. It is the technology innovation for the web we’ve all been waiting for. It is full of great functionality we always craved and it finally enables us to build huge applications for the web in a scalable and easy to maintain manner. It empowers tho...
