functional implementation with ramda

import { always, curry, ifElse, isEmpty, pipe, split, join, map }  from "ramda"

const html = curry((tagName, str) => `<${tagName}>${str}</${tagName}>`)
const h1 = html("h1")
const p = html("p")
const br = always("<br>")

const formatLines = map(ifElse(isEmpty, br, p))
const formatText = ([title, ...lines]) => [h1(title), ...formatLines(lines)]

const textToHTML = pipe(
  split("\n"),
  formatText,
  join("\n")
)
