map e chain rispettivamente in cosa si differenziano?

risposta di @gcanti su italiajs.slack.com in #fp

ambedue servono per risolvere un problema di composizione di funzioni, ma in due situazioni diverse. Partiamo dal caso più semplice, diciamo che hai due funzioni:

f: (a: A) => B
g: (b: B) => C

Questa non è farina del mio sacco, io ho solo copia incollato la discussione. Kudos to Giulio Canti

@vncz ho un consiglio su come procedere a strutturare un programma funzionale, con me ha funzionato bene, vediamo se funziona anche per te

In linea teorica e generale procedo così

  • dominio
  • firma del programma
  • firme delle operazioni di base
