Why?

We have been writing JavaScript since 2005.
Along the way we have tried several Compile-to-JS languages.
Most of them remain niche and

If you are a web application developer, and don't already know Typescript, I recommend watching Richard Feldman's ReactiveConf 2019 Talk: "Predicting the Future of the Web"

What?

Summarise the intro on https://www.typescriptlang.org

Who?

Typescript is relevant to anyone writing JavaScript in 2020 who wants to sharpen their skills in preparation for a future where Typescript is ubiquitous.

How?

With this repo we want a hybrid of https://github.com/dwyl/learn-elixir with a tour of the benefits followed by the syntax. Then we want to build a sample (basic) project to show it in action including setup, compilation, testing and deployment.
