Lightning Talk: Dart

[le0tan]

PUNCH

In 2019 GitHub Octoverse report, Dart observed a whopping 532% of growth, making it the fastest growing language of 2019, on top of some familiar names like Rust.

WIIFY

In this talk, you will learn how the design choices and unique implementation approach of Dart makes it a productive programming language that runs fast on various platforms.

Roadmap

1. What is Dart?
2. What makes Dart unique in the world of programming languages?
3. How to get started with Dart.

Key points

• Dart is productive
  • light weight: collection literals, type inference var, garbage collection
  • object-oriented
  • functional: closures, lambdas
  • typed: generics, null safety
• Dart is fast
  • background: data flow of Dart source code (lexer/parser -> kernel compiler ----> frontends)
  • fast development cycle (JIT+VM):
    • live reload
    • deep introspection services: e.g. DartPad tools for Flutter is making use of the debugging information (memory allocation,in the kernel file to map the running code back to the source file
  • fast execution: AOT+runtime
• Dart is multi-platform
  Nearly all programming languages are multi-platform, but Dart is probably one of the few that have native compilers to all major platforms while having the transpiler to JavaScript. (demo: Flutter for Web)

Impact

Know: Dart is productive and fast, and it is designed to be executed cross-platform from the beginning.
Believe: The unique flexibility in execution modes of Dart makes it compelling for any task that isn't too performance sensitive. It makes your code more future-proof.
Do: Get started with programming in Dart.
