Google's goals for Dart are to create "a structured yet flexible language for web programming," wrote Lars Bak, who is a software engineer for Google's Dart team, in a blog post officially announcing the language.
Designed for building web applications, Dart is an object oriented language, one designed to be used for both quickly cobbling together small projects, as well as for developing larger-scale web applications. Dart allows the programmer to add variables without defining their data type, called dynamic typing, or to define their data types, called static typing.
Dynamic typing is best for small projects that need to be ramped up quickly, while static typing will help secure and speed large scale web programs.
Dart is not Google's first foray into creating a new programming language to address the shortcomings of older ones. In 2009, the company debuted Go, which the company's engineers created as an alternative to the complexities of C++, Java and other traditional languages.
Bak plans to reveal more about Dart at the GoTo conference, being held this week in Aarhus, Denmark.
