Dart vs Jolie: What are the differences?
Developers describe Dart as "A new web programming language with libraries, a virtual machine, and tools". Dart is a cohesive, scalable platform for building apps that run on the web (where you can use Polymer) or on servers (such as with Google Cloud Platform). Use the Dart language, libraries, and tools to write anything from simple scripts to full-featured apps. On the other hand, Jolie is detailed as "The First Programming Language for Microservices". Jolie crystallises the programming concepts of microservices as native language features: the basic building blocks of software are not objects or functions, but rather services that can always be relocated and replicated as needed. Distribution and reusability are achieved by design.
Dart and Jolie belong to "Languages" category of the tech stack.
