Learn purescript-halogen, (v5.0.0-rc.5) from a bottom-up approach

Before learning Halogen via this project, you will need to install the following. (If you don't have them already installed, see my purescript learning repo's Install Guide

• purescript (v0.13.6)
• spago (v0.14.0)
• parcel (v1.12.4)

Or, to install them in one line

npm i -g purescript@0.13.6 spago@0.14.0 parcel

Or, instead of install globally, install relatively to this project

npm i

If you choose this approach, all aftermentioned commond like spago ... and parcel ... shall be prefix with npm run. e.g.

• npm run spago bundle-app -m ...
• npm run parcel serve ...

Required: You are already familiar with...

• PureScript's "Basic" syntax. (If not, see my Basic Syntax overview)
• PureScript's "Module" syntax. (If not, see my Module Syntax overview)
• the purescript-prelude library. (If not, see my Prelude-ish folder)
• "smart constructors." (If not, read my explanation on Smart Constructors)
• the Effect and Aff types and how they work. (If not, see my Effect and Aff folder)

Helpful, but not absolutely necessary: You are already familiar with...

• the philosophical foundations of Functional Programming. (If not, see my FP Philosophical Foundations Overview)
• PureScript's "Type-Level Programming" syntax. (If not, see my Type-Level Programming Syntax overview)
• "do notation." (If not, see my overview on Do Notation. Specifically, Discard.md to Reading Do as Nested Binds.md)
• monad transformers and how they work. (If not, see my Application Structure folder. Specifically, the MTL folder.)

1. Git clone this project
