This blog post first explains how modules work in ECMAScript 6, the next version of JavaScript. It then describes tools that allow you to already use them now.

JavaScript’s constructors have never been particularly popular: Douglas Crockford doesn’t like them and recently, more anti-constructor material has been published (two examples: blog posts by Kyle Simpson and Eric Elliott).

In this blog post, I explain that not all of the constructors’ flaws are real. But even with those that are real, I still recommend to use them. I’ll tell you why and what the future holds for constructors.

Today, there was an online event called “Hello Polymer”, in which Polymer team members Eric Bidelman, Alex Komoroske and Matthew McNulty talked about the framework. This blog post summarizes what happened.

Quick reminder: trailing commas in object literals are legal in ECMAScript 5, trailing commas in arrays are ignored.

This blog post looks at two common performance optimizations for for loops. Are they really faster than the canonical version?

The blog post describes how various functions and methods that deal with arrays are affected by holes [1].

These days, social media (Twitter, Facebook, Google+ etc.) seem much more popular than feeds (RSS, Atom). Google claims about the latter that their “usage has declined”. That begs the question: have social media made feeds irrelevant? This blog post answers that question with a firm “no” and explains why.

[2015-02-26] New version of this blog post: “Iterables and iterators in ECMAScript 6”

The iterator pattern enables unified and simple access to the elements stored in data structures. Generators are lightweight coroutines. Think: functions that can be suspended and resumed. Among other things, they help with implementing iterators.

This blog post explains how iterators and generators work in ECMAScript 6. The iterator protocol has recently changed, this post explains the new protocol.

This blog post explains how to search several websites (not just a single search engine!) from the omnibox (address bar) in Google Chrome.

Update: This blog post has become a chapter in my book “Speaking JavaScript”. You can read it here: “Basic JavaScript”.

This blog post enables you to get started with JavaScript as quickly as possible – if you already know how to program. It describes the smallest subset of the language that allows you to be productive. I call that subset “Basic JavaScript” and recommend to program in it for a while, before moving on to more details and advanced topics. Learning everything at once is too confusing. The post concludes with tips for what to learn next.
