I have this directory structure:

folder
├───file.ext
├───A
│   └───a1.ext
└───B
    └───b1.ext

And this script to read all the files in there:

import { join } from "$std/path/mod.ts";
async function readDirRecurse(dir) {
  for await (const dirEntry of Deno.readDir(dir)) {
    const subDir = join(dir, dirEntry.name);
    console.log(dirEntry.name);
    if (dirEntry.isFile) {
      array.push(subDir);
    } else if (dirEntry.isDirectory) {
      readDirRecurse(subDir);
    }
  }
}

const array = [];
await readDirRecurse("./folder");
console.log("???? ~ result:", array);

The output:

A
B
file.ext
???? ~ result: [ "folder\file.ext" ] 
a1.ext
b1.ext

My questions are:

• Why does the result is in the middle of the output, but not at the bottom?
• Why does it only contain the root file, not other files?
