Google Dart is officially a standard.

At the 107th Ecma General Assembly in Heidelberg, Germany last week, the international technology standards organization approved the first edition of the Dart Programming Language Specification. Ecma first established a technical committee to publish the standard last December.

Since its 1.0 release last November, Google’s Web development language has been releasing new versions at a fast clip. Dart 1.5, with added mobile development features, came out last week.

While Dart’s standardization may slow down its rapid development pace (due to Ecma committee meetings held every two months, and other bureaucratic processes), Google is finally getting what it wanted for Dart: an official stamp of approval. One of the biggest barriers to the language’s mainstream browser adoption has just been lifted.
