I came across this the other day, while I was reading “ng-Book 2” from fullstack.io. They introduced a REPL module for Typescript. It’s called tsun. It works just like a REPL in Ruby or Python. It provides an interactive shell, where you can test out code and see instant results to your commands. This is a great way to test out ideas or code concepts.
To install tsun, you must have npm installed (node) and you just simply run:
npm install -g tsun
that will install tsun globally.
Once installed you just run:
and you’ll have a “>” prompt. At this point you can simply type in Typescript and get results in the interactive shell.
