1fill in blank

easy

💡 Hint

Common Mistakes

Using __dirname instead of process.cwd()

Trying to call process.chdir() which changes directory

Using require which is for modules

The process.cwd() function returns the current working directory of the Node.js process.

2fill in blank

medium

Complete the code to print the directory name of the current module file.

Node.js

console.log([1]);

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

A__dirname

Bmodule.filename

Cprocess.cwd()

Dprocess.env.PWD

💡 Hint

Common Mistakes

Using process.cwd() which is the working directory, not the file's directory

Trying to call __dirname as a function

Using module.filename which gives the full file path

The __dirname variable holds the directory path of the current module file.

3fill in blank

hard

Fix the error in the code to correctly print the current working directory.

Node.js

console.log(process.[1]);

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

Bcwd[]

Ccwd

Dcwd{}

💡 Hint

Common Mistakes

Using process.cwd without parentheses

Trying to access cwd as an array or object

process.cwd() is a function and must be called with parentheses to get the current working directory.

4fill in blank

hard

Fill both blanks to create an absolute path to a file named 'data.txt' in the current module's directory.

Node.js

const path = require('path');
const filePath = path.join([1], [2]);
console.log(filePath);

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

A__dirname

B'data.txt'

Cprocess.cwd()

D'./data.txt'

Attempts:

3 left

💡 Hint

Common Mistakes

Using process.cwd() instead of __dirname for the directory

Using './data.txt' which is a relative path and may not resolve correctly

Use __dirname to get the current module's directory and join it with the filename 'data.txt' to get the absolute path.

5fill in blank

hard

Fill both blanks to create a function that returns the absolute path of a file given its name, relative to the current module's directory.

Node.js

const path = require('path');
function getFilePath(filename) {
  return path.join([1], [2], filename,);
}

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

A__dirname

B'src'

C,

D'/'

💡 Hint

Common Mistakes

Using slashes '/' inside path.join arguments instead of separate arguments

Forgetting commas between arguments

Using process.cwd() instead of __dirname

The function joins __dirname, a subfolder 'src', and the filename. The commas separate the arguments in path.join.
