Reduce paths

The forEach could be replaced with a reduce but I think it's less readable.

Code

  • function getTree(strings) {
  const tree = {};
  strings.forEach(path => {
    path && path.split("/").reduce((acc, cur, idx, src) => {
      if (idx >= src.length - 1) {
        acc[cur] = 'file';
      } else {
        acc[cur] = acc[cur] || {};
      }
      return acc[cur];
    }, tree);
  });
  return tree;
}
    • function getTree(strings) {
    • return strings.reduce(
    • (root, path) => {
    • let items = path.split("/").filter(x=>x);
    • if (!items.length) return root;
    • let branch = root;
    • while (items.length > 1) {
    • let item = items.shift();
    • branch=branch[item]=branch[item]||{};
