Why? What? Who? How?

# Why?

We have been writing JavaScript since [2005](https://www.amazon.co.uk/DOM-Scripting-Design-JavaScript-Document/dp/1590595335).
Along the way we have tried several [Compile-to-JS languages](https://github.com/jashkenas/coffeescript/wiki/List-of-languages-that-compile-to-JS).
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"

> "_I think the next big thing on the web will be `Typescript`. I don't think `Elm` will take over the world, I think `Typescript` will._" ~ Richard Feldman 2019

Baring in mind that Richard has a _significant_ investment of time/effort in `Elm` https://www.manning.com/books/elm-in-action and NoRedInk (his employer) are the single biggest `Elm` user, he sees the trends as "writing on the wall"; `Typescript` will take over.

# What?

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


The main benefits are:
+ [ ] Type safety
+ [ ] Gradual/incremental adoption
+ [ ] Superset of JS so all JS code works.
+ [ ] add more as you summarise what you learn ...

# 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.
