Srujan Gaddam 3b294fdab2 [dart:js_interop] Add isA helper
Closes https://github.com/dart-lang/sdk/issues/54138

Adds a helper to do better type-checks so that users don't
accidentally using is checks or have to manually do the right
typeof or instanceof checks. In order to do this, there is
some refactoring to make ExportCreator a SharedInteropTransformer
(as it's shared across all backends) so that we can reuse an
existing visitor. In the same class, we remove unnecessary setting
of parent pointers. We should clean up the fileOffsets as well,
but dart2js verifies that those are set, so we keep them as is
for now. Also adds some static errors for edge cases.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
