04-copy-directory

Copying a Directory

In the index.js file of the 04-copy-directory folder, implement the copyDir function, which copies the contents of the files folder to the files-copy folder.

General Rules

• The use of any third-party modules is prohibited.
• Each task must be executed in the root directory using the command node <task folder name>.
• The use of synchronous functions from the fs module, such as fs.statSync(path[, options]), fs.readFileSync(path[, options]), and others found in the synchronous API section, is prohibited.

Requirements

• After the function execution terminates, a files-copy folder is created, the contents of which are an exact copy of the original files folder.
• When files are added/removed/modified in the files folder and the node 04-copy-directory is rerun, the contents of the files-copy folder are updated.
• The use of fsPromises.cp() is prohibited.

Objectives

• Learn to copy files and directories.

Description

Steps to complete the task:

1. Import all required modules.
2. Create the files-copy folder if it does not exist yet.
3. Read the contents of the files folder.
4. Copy files from the files folder to the files-copy folder.

Tips

Pay attention to the recursive option that can be passed to fsPromises/mkdir. With its help, you can avoid errors in cases where the directory already exists.
