This Node.js script is designed to print a visual representation of the directory structure of the current directory where the script is located. Here's a step-by-step explanation:

1. Imports and Function Definition:

const fs = require('fs');
const path = require('path');

• fs is the Node.js File System module used to read and interact with the filesystem.
• path is a Node.js module used to handle and transform file paths.

2. printTree Function:

function printTree(dir, indent = '') {
    ...
}

• This function takes a directory path dir and an optional indent string used for formatting the output.

const items = fs.readdirSync(dir).filter(file => !file.startsWith('.'));

• Read all items ( files and directories ) in the given directory dir
• Filters out hidden files ( those start with a dot . ).

const directories = items.filter(file => fs.statSync(path.join(dir, file)).isDirectory());
const files = items.filter(file => !fs.statSync(path.join(dir, file)).isDirectory());

• Separates items into directories and files by checking if each item is a directory or not directory.

const sortedItems = [...directories, ...files].sort((a, b) => {
    const aStat = fs.statSync(path.join(dir, a));
    const bStat = fs.statSync(path.join(dir, b));

    if (aStat.isDirectory() && !bStat.isDirectory()) return -1;
    if (!aStat.isDirectory() && bStat.isDirectory()) return 1;
    return a.localeCompare(b);
});

• Combines directories and files into one list, with directories coming before files.
• Sort the combined list. Directories come before files in the list.
• If both are of the same type, it sorted Alphabetically.

sortedItems.forEach((item, index) => {
    const fullPath = path.join(dir, item);
    const isDirectory = fs.statSync(fullPath).isDirectory();
    const last = index === sortedItems.length - 1;

• Iterates over each item in the sorted list.
• Determines if the item is a directory and if it is the last item in the list ( for use formatting purposes ).

const displayName = isDirectory ? `./${item}` : item;

console.log(`${indent}${last ? '└── ' : '├── '}${displayName}`);

• Set a displayName to prefix directions witch ./.
• Print the item with a grapical tree representation. Uses └── for the last item and ├── for the others.

if (isDirectory) {
    printTree(fullPath, `${indent}${last ? '    ' : '│   '}`);
}

• If the item is a directory, it recursively calls printTree to print its content, with adjusted indentation.

3. Execution:

const currentDirectoryPath = path.dirname(__filename);
const currentDirectoryName = path.basename(currentDirectoryPath);
console.log(currentDirectoryName);
printTree(currentDirectoryPath);

• path.dirname(__filename) gets the directory path of the current script.
• path.basename(currentDirectoryPath) gets the name of that directory.
• Print the name of this directory.
• Call printTree to print the directory structure of the current directory.

Overall, this script will produce a text-based tree view of the directory structure where it is executed, showing directories and files in a structured, indented format.
