// Insert path into directory tree structure:
//
//modified to construct an object instead of an array.

function insert(tree = {}, [head, ...tail]) {

  if (tail.length > 0) {
    tree[head] = insert(tree[head], tail)
  } else {
    tree[head] = true
  }

  return tree;
}

// Example:
let examplepaths = [
  'css/style.css',
  'about/bird.svg',
];

//naive! assumes relative path like in example.
//A more robust implementation would need to resolve paths first, but to what.
export default function process(paths) {
  return paths
  .map(path => path.split('/')
    //.slice(1) //if path starts with / or ./
  )
  .reduce((tree, path) => insert(tree, path), {});
}

//test:
// console.log(process(examplepaths));
