This blog post explains the so-called TC39 process, which governs how ECMAScript features are designed, starting with ECMAScript 2016 (ES7).

This blog post examines three ways of executing function sequentially:

• Synchronously
• Asynchronously, via Promises
• Asynchronously, via the library co

The ECMAScript 6 specification defines in which order the properties of an object should be traversed. This blog post explains the details.

This is a list of a few ECMAScript 6 features and what their influences were:

This blog post describes the proposed ECMAScript feature “call constructor” (stage 1).

In ECMAScript 6, accessing a let or const variable before its declaration (within its scope) causes a ReferenceError. The time span when that happens, between the creation of a variable’s binding and its declaration, is called the temporal dead zone.

For more information, consult Sect. “The temporal dead zone” in “Exploring ES6”. Here, I’d like to answer two questions:

• Why is there a temporal dead zone?
• Why does typeof cause a ReferenceError for a variable in the TDZ?

The classic command for running a simple web server from a shell is:

python -m SimpleHTTPServer [«port»]

As a result, files are served at http://localhost:«port», with 8000 being the default if you omit the port.

Static site generation: minimizing how much is re-generated  #

When statically generating HTML content, you face an interesting challenge: If the page frame (the “chrome” of a page) contains information that changes frequently, you need to re-generate all pages every time it does. One example of such information is a top 10 list of the pages that were most popular during the last 30 days.
