What isdart2js

Dart2js compiler is the ultimate tool for converting Dart code to JavaScript, and it has just gotten better. The global type inferencer feature in the latest update provides optimized and faster code. Global type inferencer analyzes the entire program and removes redundant checks and bailouts producing optimized code that runs smoothly.

Dart is a versatile language for developing fast apps on any platform. It aims to provide an effective programming language that can work efficiently on multiple platforms with a flexible runtime environment for app frameworks.

In Dart 2.18, the dart2js command line tool has been removed, but fret not, the dart2js compiler is still present. Instead, developers can use the dart compile js function to transform their Dart code into JavaScript, which is easier to use.
