How Dart Works

How Dart Works

Dart uses Multiple Compiler such as JIT, AOT , Dart2JS, Dart2native.

Just in Time Compiler - As it name says , compile small piece of code which is need it to execute rather than compiling the entire code and it is mostly need it for Hot Reload. Use in Development only.

Ahead of Time Compiler - Compiles the entire code and convert it into platform specific native code, it also make sure the compiled code is best optimised for particular platform. Used for Production release.
