Dart

Information Technology > Programming languages

Description

Dart is a versatile programming language developed by Google and used for building web, server, and mobile applications. It's object-oriented, meaning it organizes data into 'objects' that can interact with one another. Dart is known for its strong typing and rich standard libraries. It supports asynchronous programming, allowing tasks to run concurrently, improving performance. Dart also offers advanced features like isolates for parallel programming. Its package manager, 'pub', simplifies the process of managing and publishing packages. Dart is the primary language for Flutter, Google's UI toolkit for building natively compiled applications, making it a popular choice for mobile app development.
