Google Throws New ‘Dart’ Programming Language at the Web
But, regardless of how well those three have served the web thus far, they are not enough for Google, which is hoping the web will now embrace Dart, Google’s brand-new programming language for “structured web programming.”
That solution is Dart, a “class-based optionally typed programming language for building web applications.”
Lars Bak, a software engineer working on Dart, says the language is designed to work with every thing from “a one-person project without much structure to a large-scale project needing formal types in the code to state programmer intent.”
In other words, Dart is aiming to be a one-size-fits-all solution for writing apps on the web. Dart has been built from the ground up with this goal in mind. Indeed Dart offers some interesting tools, including optional types and the ability to declare private methods via an underscore. Unfortunately for Dart, a couple of novelties don’t seem to be winning over programmers. The Hacker News discussion thread on Dart is full of rather barbed critiques with hardly a supportive voice to be heard.
Dart on the web
Appealing to programmers is only half of what Dart needs to succeed; it also has to work well on the open web. For that Google has two solutions.
Essentially, Google has set up a two-tier system for running Dart in the browser, and that is where Dart might run afoul of the open web.
Prior Dart Art
While Dart is open source and available for anyone to use, Google does not have a strong record of fostering open projects; that is, projects where the community can not just download and compile code (Andy Rubin’s “definition of open“) but can actually have a hand in creating features and guiding the direction of the project.
Until the latter component is well established, don’t expect other browser makers to adopt Dart. So long as Google controls the strings it’s unlikely its arch rivals like Microsoft and Apple will support Dart.
What standards proponents fear is a web where only Google’s Chrome browser ever fully supports Dart. That would mean that, while Dart apps would work everywhere, they’d be significantly faster in Chrome. That would send the web back to the bad old days of “works best in Internet Explorer” websites, only this time around it would be “works best in Google Chrome.”
It’s possible that Google will use Dart to finally create a true community-driven project. The company has already said it plans to eventually submit Dart for standardization, which would certainly help.
It’s too early to write off Dart, but it’s also too early to say it will be anything more than a novelty Google uses in its own apps (like WebP or even SPDY). Even if Dart can convince both developers and browser makers to jump on board, don’t look for Dart to become the “lingua franca of web development” any time soon.
