💡 Hint

Common Mistakes

Using process.env which gives environment variables, not version.

Using process.platform which gives OS platform, not Node.js version.

The process.version property returns the Node.js version as a string.

2fill in blank

medium

Complete the command to check Node.js version in terminal.

Cypress

node [1]

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

A--list

B--help

C--version

D--check

💡 Hint

Common Mistakes

Using --help which shows help info, not version.

Using --list which is not a valid option.

The node --version command prints the installed Node.js version in the terminal.

3fill in blank

hard

Fix the error in this Node.js script that prints version.

Cypress

console.log('Node.js version:', process.[1]);

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

Dversion

💡 Hint

Common Mistakes

Using process.versions which is an object, not a string.

Using made-up properties like ver or versionNumber.

The correct property is process.version. Others do not exist or are incorrect.

4fill in blank

hard

Fill both blanks to create a script that checks if Node.js version starts with 'v14'.

Cypress

if (process.[1].[2]('v14')) {
  console.log('Node.js version is 14.x');
}

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

BstartsWith

Cincludes

Dslice

💡 Hint

Common Mistakes

Using process.versions which is an object, not a string.

Using includes instead of startsWith which checks anywhere in string.

process.version gives the version string, and startsWith('v14') checks if it begins with 'v14'.

5fill in blank

hard

Fill all three blanks to create a script that extracts major Node.js version number as an integer.

Cypress

const versionString = process.[1];
const majorVersion = parseInt(versionString.[2](1, versionString.[3]('.', 1)));
console.log(`Major version: ${majorVersion}`);

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

Aversion

Bslice

CindexOf

Dsubstring

💡 Hint

Common Mistakes

Using substring instead of slice which also works but here slice is expected.

Not removing the 'v' before parsing the number.

Using indexOf with wrong character.

process.version gives the version string like 'v14.17.0'. slice(1) removes the 'v'. indexOf('.') finds the first dot to extract the major version number.
