Though compiling down to JavaScript takes care of the core issue of running your Dart projects in these other browsers, it doesn’t address Google’s aim of having it replace JavaScript as the lingua franca of the web. The teams behind Firefox, Safari, Internet Explorer, and Opera have no plans to add a Dart VM into their browsers at this time. Work has already begun on bringing the Dart VM into mainline Chrome, b ut not everyone thinks Google have the answer just yet. ![]() And all of this is mooted by the fact that no browser – Chrome included – ships with a Dart VM.īut for Chrome users, the future of Dart is tentatively optimistic.

Though Chrome itself doesn’t include a Dart VM, the included dart2js tool will compile your code into JavaScript, making your Dart-powered web apps suitable to use in every “modern” browser. The editor comes bundled with the Dart download and running a project will open up a custom-built version of Chromium called Dartium that includes a Dart virtual machine. The Eclipse-based Dart Editor is the perfect development environment for anyone just trying out Dart or wanting up-to-date editor support for the latest Dart releases. Whether you’ve been waiting for the dust to settle before getting into the language or are taking your first steps into web development, Google provides a number of tools to make coding and debugging Dart easier. The 1.0 release marks the first stable version of the programming language since development began in 2011 and several benchmarks already show Dart performing better than JavaScript.īut what does this mean for you as a consumer, a fledgling web developer, or even an established JavaScript developer?
