Modern JavaScript from the Beginning - Second Edition - path Module

The video tutorial introduces the path module, a core module in Node.js that helps manage file and directory paths. It covers various methods like basename, extname, dirname, join, and resolve, explaining their usage in handling file paths across different operating systems. The tutorial also discusses environment variables like __dirname and __filename, which provide absolute paths to the current directory and file. These tools simplify path management, ensuring compatibility across Windows, Linux, and Mac systems.

What is a key reason for using the path module in Node.js?

• To manage path separators across different operating systems

• To create new files

• To delete directories

• To manage user permissions

What does the basename method return when given a file path?

• The directory name

• The file extension

• The base name of the file

• The full path

How can you use the basename method to exclude the file extension?

• By modifying the file path

• By using a different method

• By passing the extension as a second argument

• By using a regular expression

What does the extname method return?

• The directory name

• The base name of the file

• The file extension

• The full path

What is the purpose of the dirname method?

• To create a new directory

• To get the directory name

• To get the file extension

• To get the base name of the file

What is the main difference between the join and resolve methods?

• Join creates absolute paths, resolve creates relative paths

• Join creates relative paths, resolve creates absolute paths

• Join is used for directories, resolve is used for files

• Join is faster than resolve

What does the __dirname variable provide?

• The name of the file

• The absolute path of the directory containing the current file

• The file extension

• The relative path of the directory
