💡 Hint

Common Mistakes

Using 'fs' or 'http' instead of 'path' in require.

Forgetting to use quotes around the module name.

The path module is used to handle file paths in Node.js. Importing it with require('path') allows you to use its functions.

Complete the code to join directory and file name into a path.

Node.js

const fullPath = path.[1]('folder', 'file.txt');

💡 Hint

Common Mistakes

Using basename which returns the last part of a path.

Using extname which returns the file extension.

The join method combines path segments into one path string, handling separators correctly.

Fix the error in the code to get the file extension.

Node.js

const ext = path.[1]('index.html');

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using basename which returns the file name.

Using dirname which returns the directory path.

The extname method returns the file extension from a path string.

4fill in blank

hard

Fill both blanks to get the directory name and base file name from a path.

Node.js

const dir = path.[1]('/home/user/file.txt');
const base = path.[2]('/home/user/file.txt');

Drag options to blanks, or click blank then click option'

Adirname

Bextname

Cbasename

Djoin

💡 Hint

Common Mistakes

Mixing up basename and dirname.

Using extname instead of basename.

dirname returns the directory part of the path, and basename returns the file name.

5fill in blank

hard

Fill all three blanks to normalize a path, get its absolute path, and extract the extension.

Node.js

const normalized = path.[1]('folder//subfolder/../file.txt');
const absolute = path.[2](normalized);
const extension = path.[3](absolute);

Drag options to blanks, or click blank then click option'

Cextname

Dbasename

💡 Hint

Common Mistakes

Using basename instead of extname for extension.

Skipping normalization before resolving.

normalize cleans up the path, resolve makes it absolute, and extname gets the file extension.
