Answer 1

Here is my try on your SPECIFIC example. I know it is an old question but I have used current methods

const titlesCsv = `id;name;author
integer;string;authors:n
1;To Kill an Mockingbird;1
2;Lord of the Rings;2
3;Hamlet;3`

const authorsCsv = `id;name
integer;string
1;Harper Lee
2;JRR Tolkien
3;William Shakespeare`

const parseCsv = csv => {
  let lines = csv.split("\n");
  const header = lines.shift().split(";")
  lines.shift(); // get rid of definitions
  return lines.map(line => {
    const bits = line.split(";")
    let obj = {};
    header.forEach((h, i) => obj[h] = bits[i]); // or use reduce here
    return obj;
  })
};
const titles = parseCsv(titlesCsv)
const authors = parseCsv(authorsCsv)
const books = titles.map(title => {
  return {
    id: title.id,
    name: title.name,
    author: authors.find(author => author.id === title.author).name
  }
})

console.log(books)
