Practice - 5 Tasks

1fill in blank

easy

Complete the code to parse a file path into its parts using path.parse.

Node.js

const path = require('path');
const parsed = path.[1]('/home/user/file.txt');
console.log(parsed);

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

💡 Hint

Common Mistakes

Using path.format instead of path.parse

Using path.basename which only returns the file name

The path.parse method breaks a file path into its parts like root, dir, base, ext, and name.

medium

Complete the code to create a path string from an object using path.format.

Node.js

const path = require('path');
const obj = { root: '/', dir: '/home/user', base: 'file.txt' };
const fullPath = path.[1](obj);
console.log(fullPath);

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

💡 Hint

Common Mistakes

Using path.parse which does the opposite

Using path.resolve which resolves absolute paths

The path.format method builds a path string from an object with parts like root, dir, base, etc.

3fill in blank

hard

Fix the error in the code to correctly parse the path '/var/log/sys.log'.

Node.js

const path = require('path');
const parts = path.[1]('/var/log/sys.log');
console.log(parts.ext);

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

💡 Hint

Common Mistakes

Using path.format which expects an object

Using path.basename which returns only the file name

To get parts of a path, use path.parse. Using format or others will cause errors or wrong results.

4fill in blank

hard

Fill both blanks to parse a path and then format it back to a string.

Node.js

const path = require('path');
const parsed = path.[1]('/etc/nginx/nginx.conf');
const formatted = path.[2](parsed);
console.log(formatted);

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

💡 Hint

Common Mistakes

Using format before parse

Using join or basename which do different things

First, use parse to split the path, then format to join it back into a string.

5fill in blank

hard

Fill all three blanks to parse a path, change its base, and format it back.

Node.js

const path = require('path');
const parsed = path.[1]('/usr/local/bin/script.sh');
parsed.base = '[2]';
parsed.name = '[3]';
const newPath = path.format(parsed);
console.log(newPath);

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

💡 Hint

Common Mistakes

Changing base but not name

Using format instead of parse to get parts

Use parse to get parts, then change base and name, and finally format to build the new path.
