Understanding __dirname and __filename
When working with files and directories in Node.js, you often need to know the path of the file that is currently being executed or the directory that contains it. Node.js provides two special global variables for this: __dirname and __filename.
__dirname gives you the absolute path of the directory containing the currently executing file. This is useful when you want to build paths to other files or directories relative to your script, such as reading configuration files or serving static assets. __filename provides the absolute path to the file itself, including the filename. You would use this if you need to reference the script file directly or log its location. Both __dirname and __filename always resolve to absolute paths, so you do not have to worry about the current working directory of your process.
You should use __dirname when you need to work with other files in the same directory or a known relative location. Use __filename if you need the full path to the current script file, such as for logging, debugging, or passing the script location to another process.
index.js
In browser JavaScript, there are no __dirname or __filename variables. Browsers do not provide access to the local file system for security reasons, so you cannot directly get the file path of the script or its containing directory like you can in Node.js.
