Not Ninjas, Just Programmers

  var ninja = {
    sneakAround: function() {...},
    strikeFromShadows: function() {...},
    writeStableWebApp: function() {...}
  }; 

Terms like JavaScript ninja or JavaScript wizard tend to make me uneasy. They suggest a set of priorities in programming that I would argue are counterproductive. To begin discussing why, let’s refer to some definitions:

  • ninja [nin-juh], noun: a member of a feudal Japanese society of mercenary agents, highly trained in martial arts and stealth (ninjutsu) who were hired for covert purposes ranging from espionage to sabotage and assassination.
  • wizard [wiz-erd], noun: a person who practices magic; magician or sorcerer.

I wouldn’t consider any of the qualities implied here as important, or even attractive, in software development. Why would anyone want code to be stealthy? Or covert? Or magic? Glorifying these qualities betrays an attitude that shifts focus away from the software we build to the cleverness of the code that’s used to build it. Exploiting syntactic idiosyncrasies in novel ways or displaying one’s knowledge of the esoteric details of a language takes priority over creating robust, maintainable applications. It’s programming as performance, rather than programming as craft.

Constructors Are Bad For JavaScript

JavaScript is a language that has always been at odds with itself. It derives its core strength from a simple, flexible object model that allows code reuse through direct object-to-object prototypal inheritance, and a powerful execution model based on functions that are simply executable objects. Unfortunately, there are many aspects of the language that obscure this powerful core. It is well-known that JavaScript originally wanted to look like other popular languages built on fundamentally different philosophies, and this trend in its history has lead to constructs in the language that actively work against its natural flow.
