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...
It’s not often that we, as PHP developers, need to worry about memory management. The PHP engine does a stellar job of cleaning up after us, and the web server model of short-lived execution contexts means even the sloppiest code has no long-lasting effects. There are rare times when we may need to step outside of th...
The debut of Promises in JavaScript has lit the internet on fire—they help developers break out of callback hell and solve a lot of problems that have plagued the asynchronous code of JavaScript programmers everywhere. Promises are far from flawless, though. They still require callbacks, can still be messy in complex...
Arrays, and by extension iteration, are fundamental parts to any application. And like the complexity of our applications, how we use them should evolve as we gain access to new tools. New tools, like generators, for instance. First came arrays. Then we gained the ability to define our own array-like things (called ite...
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...
