Path Module
Work with file and directory paths across platforms
javascript
const path = require('path');
// Join paths
path.join('/users', 'john', 'documents', 'file.txt');
// Get parts
path.dirname('/users/john/file.txt'); // /users/john
path.basename('/users/john/file.txt'); // file.txt
path.extname('file.txt'); // .txt
// Resolve absolute
path.resolve('file.txt');🟢 Essential - Handle paths correctly on all OS
💡 Always use path.join() not string concatenation
📌 __dirname is current file's directory
⚡ path.resolve() creates absolute paths
⚠️ Windows uses \ while Unix uses /
