The Practice of "Vanilla JS"


I try to keep my skills up and its hard to do when the thing you try to have skills in is always changing. The web landscape is always in flux, at a seemingly ever-increasing pace. Javascript represents only one area of the web, and as a language within a much greater ecosystem even that microcosm can keep you busy with the evolution of the language itself (ES6), constantly rolling out new in-browser APIs (like the new Web Cryptography API), and learning to sling this language both inside browsers and on backends (Node.js).

One of the best tools I have to keep these skills sharp is the practice of what you call “Vanilla Javascript”. I try hard to find lots of small opportunities to practice Javascript without the abstractions of all the myriad of libraries and frameworks that might obscure it even in the course of a single day’s work. I find two simple strategies help me poke through the cushion these tools provide to make sure I don’t forget what’s under the hood.

  • On a new project, especially a smaller one, I’ll build what I can using no JS libraries until the need really presents itself. Its wonderful how many tasks you’d turn to jQuery in the past for are just fine to approach using nothing but standard APIs today.
  • At any time, I try to have one toy project i might come back to when I have some time to kill, which I keep a “plain only” rule on. These are just private throwaway projects, but useful to give me a sandbox to avoid the pressures that usual projects bring to the table with a necessity of a toolchain’s safety net.

The effort is small, but the impact of keeping yourself reminded of the language and APIs underneath jQuery, Angular, React, or whatever other JS toolset you prefer is undoubtedly valuable. 

The next time you’ve got a new task JS to complete, give yourself a quick challenge in accomplishing it without a library. But, find a balance, and don’t force yourself to do what you really should use a library for. Just give yourself that chance, now and then, to discover some new Vanilla JS you may have not known before or to revive some understand which had gotten rusty.

CARDIAC: The Cardboard Computer

I am just so excited about this. CARDIAC. The Cardboard Computer. How cool is that? This piece of history is amazing and better than that: it is extremely accessible. This fantastic design was built in 1969 by David Hagelbarger at Bell Labs to explain what computers were to those who would otherwise have no exposure to them. Miraculously, the CARDIAC (CARDboard Interactive Aid to Computation) was able to actually function as a slow and rudimentary computer.  One of the most fascinating aspects of this gem is that at the time of its publication the scope it was able to demonstrate was actually useful in explaining what a computer was. Could you imagine trying to explain computers today with anything close to the CARDIAC? It had 100 memory locations and only ten instructions. The memory held signed 3-digit numbers (-999 through 999) and instructions could be encoded such that the first digit was the instruction and the second two digits were the address of memory to operate on

Statement Functions

At a small suggestion in #python, I wrote up a simple module that allows the use of many python statements in places requiring statements. This post serves as the announcement and documentation. You can find the release here . The pattern is the statement's keyword appended with a single underscore, so the first, of course, is print_. The example writes 'some+text' to an IOString for a URL query string. This mostly follows what it seems the print function will be in py3k. print_("some", "text", outfile=query_iostring, sep="+", end="") An obvious second choice was to wrap if statements. They take a condition value, and expect a truth value or callback an an optional else value or callback. Values and callbacks are named if_true, cb_true, if_false, and cb_false. if_(raw_input("Continue?")=="Y", cb_true=play_game, cb_false=quit) Of course, often your else might be an error case, so raising an exception could be u

How To use Sphinx Autodoc on ReadTheDocs with a Django application

Sphinx is awesome for writing documentation. ReadTheDocs is awesome for hosting it. Autodocs are great for covering your entire API easily. Django is a great framework that makes my job easier. Between these four things is an interaction that only brought me pain, however. I'm here to help the next dev avoid this. Autodocs works by importing your modules and walking over the classes and functions to build documentation out of the existing docstrings. It can be used to generate complete API docs quickly and keep them in sync with the libraries existing docstrings, so you won't get conflicts between your docs and your code. Fantastic. This creates a problem when used with Django applications, where many things cannot be imported unless a valid settings module can be found. This can prevent a hurdle in some situations, and requires a little boilerplate to get working properly with Sphinx. It require a little extra to get working on ReadTheDocs. What makes this particularly h
