...or, a brief introduction to machine omletting. Thinking back on when I started programming as a kid, I could pretty well sum up the playing around that I did then (and to be honest most of the work I do now) as writing a recipe. The "deliverable" was

An interesting tactic when researching language features is to re-create newer features, using prior, earlier supported features. For example, is it possible to approximate the features and syntax flow provided by async/await, but using only generators and Promises? -------------------------------------------------------------------------------- Baseline example in native async/await The canonical example of

I took the time to illustrate the similarities between traditional JavaScript prototypal inheritance using constructor functions to manage inheritance, and the syntax afforded by ES2015 classes. I originally did this to help clear up some incomplete understanding on my team, but I thought that other folks might benefit from seeing

In order to better illustrate their internal differences, I thought it would be interesting to create polyfills for some Array.prototype methods. What follows is the code for polyfills, example usage, and a little discussion. -------------------------------------------------------------------------------- Here is a polyfill for Array.prototype.map() [https://developer.mozilla.org/en-US/docs/

Nothing special here, but still worth reviewing, and with a few explanations: Number (e.g. double): +arg Int32: ~~arg or arg|0 Uint32: arg >>> 0 String: ''+arg Boolean: !!arg -------------------------------------------------------------------------------- Sources: Trevor Norris, Introduction to the three key areas of performance [https://gist.github.com/

* false * 0 (zero) * "" (empty string) * null * undefined * NaN In JavaScript, what do all of the above values have in common? If you guessed "they are all falsey", you are correct, and you have won yourself a copy of The Hole in the Zero [http://www.amazon.

Underscore [http://underscorejs.org/docs/underscore.html] has been making my life easier, and I've been explaining the Star Wars pantheon to my son so often, that it was unavoidable that the two should at some point intersect. So I thought I'd give a few simple

Overall, my initial impressions were mixed. I was very interested in parsing a new language with PegJS, mildly interested in code analysis tools, and lost interest when it came to fabricating a crude drum pad instrument. But whatever your pleasure or poison, hopefully the earnest appeal for community and improving
