Idiom #211 Create folder

Create the folder at path on the filesystem

use std::fs;
fs::create_dir(path)?;

This doesn't create parent directories. fs::create_dir_all does.
use std::fs;
fs::create_dir_all(path)?;

create_dir_all creates intermediate parent folders as needed
import { mkdir } from 'fs/promises';
await mkdir(path);
FileUtils.mkpath( path )

import os
os.mkdir(path)
import "os"
err := os.Mkdir(path, os.ModeDir)

This works only if path's parent already exists.
import "os"
err := os.MkdirAll(path, os.ModeDir)

MkdirAll creates any necessary parents.
