JavaScript: Key array does not store the value

I expect a list of all keys & values from the arrays to be displayed at the end.

But the key array only remembers the key: value from the last for loop operation.

let o = 0
let max
while (true) {
  [dir, dirs, files] = dir_content(dir, dirs, files)
  for (let i = 0; i < files.length; i++) {
    let blocked_dir = true;
    for (let b = 0; b < blocked_dirs.length; b++) {
      if (files[i] == blocked_dirs[b]) {
        blocked_dir = false
      } else {}
    }
    if (blocked_dir) {
      tree.dir = files[i];
      //Object.assign(tree, {dir: files[i]});
    }
  }
  console.log(tree)
  break
}
