They tried to cover this up. In designing ECMAScript 2015 (a.k.a. ES6, a.k.a. ES2015), the authors identified a number of undesirable side effects of their work. “Why worry?” they asked. “People will be so smitten with arrow functions and block-scope bindings that they won’t care about a few measly backwards-breaking changes.” Well I care, and I have evidence that suggests I’m not alone. Through a
Stabilizing ECMAScript 2015 (ES6): Teaming up with TC39 and Google on Test262 August 14, 2015. Mark your calendars. That’s my next birthday. Another important date is June 18, 2015–it’s when the ECMA General Assembly will vote on and approve the 6th edition of Ecma-262 and usher in the next era of JavaScript. On that day, all those new language features we’ve been coveting/dreading will officially
One of my favorite things about programming in node is the package management system. In almost all instances, the practice of locally installing modules for each project has simplified my life as a developer. However, as a long time contributor to Grunt, I have become intimately familiar with one edge case where this practice breaks down. In the hope of mitigating the annoyance for everyone, I cr
AMD (short for Asynchronous Module Definition) is a JavaScript API specification for structuring modular code. The web abounds with blog posts illustrating its use in front-end application development (and there’s plenty of healthy debate around its necessity, too). The topic of unit testing (despite being integral to the process of software development) does not receive much attention in these di
Building a back-end API layer introduces a whole new layer of coordination between server and client code. While there are many aspects to this delicate dance of communication, one key ingredient to minimizing back-and-forth-confusion-about what-call-does-what, is consistently communicating about your API endpoints. This is by no means rocket science, but over time I’ve created a template that I n
00000001 // 1 — truthy, so LED 7 is ON Throw in the iteration from 0 to 255, a timeout, and some Johnny Five code, and we end up with this: Part 2: Learning to Write If all we wanted to do was count from 0 to 255 in blinking lights, then the best we can say about bitwise operators is that they save us a few lines. A few days after I got the LEDs blinking, I saw this code for making a two-line liqu
I’ve just returned from the future, and I have a lot to share with you. World news, sports scores, market changes, all that stuff can wait. First, we need to talk about third-party JavaScript. There’s a great deal of browser technology on the way that will affect the way you write code. Here, I’ll focus specifically on tech that has relevance to third-party JavaScript (3PJS) developers. I’ve edito
Over the past year Bocoup has worked on several production applications that utilize the MVC library Backbone.js. We’ve worked hard to give back to the community through informative blog posts, core contributions, support & evangelism through various mediums such as meetups, IRC and Twitter. Over the course of the past year, we created small boilerplates to share around the office and across proje
Updated on August 20th, 2015 – This blog post was originally written to use the Twitter public API. That API has since changed to not allow unauthenticated queries. We’ve updated this post to utilize the GitHub API instead which still allows a minimal amount of unauthenticated queries (60 an hour.) The linked jsFiddles have been updated to reflect this but you may encounter the rate limiting rathe
