Importing Node.js Core Modules

This video tutorial introduces the Node.js module system, focusing on the file system module. It demonstrates how to use the FS.writeFileSync method to write data to files and explains error handling and debugging. A challenge is presented to use appendFileSync to append data, encouraging hands-on practice. The tutorial emphasizes the importance of following along and engaging with challenges to gain real-world experience.

What is the primary purpose of the Node.js module system?

• To organize and reuse code

• To manage user interfaces

• To handle database connections

• To improve network security

Which module allows you to interact with the file system in Node.js?

• File System module

• Path module

• Console module

• HTTP module

What does the FS.writeFileSync method do?

• Appends data to a file

• Deletes a file

• Writes data to a file synchronously

• Reads data from a file

What is the difference between FS.writeFile and FS.writeFileSync?

• FS.writeFile is synchronous, FS.writeFileSync is asynchronous

• Both are synchronous

• FS.writeFile is asynchronous, FS.writeFileSync is synchronous

• Both are asynchronous

What is the purpose of the require function in Node.js?

• To load modules into a script

• To execute shell commands

• To compile JavaScript code

• To manage HTTP requests

How do you load a core Node.js module using require?

• By specifying the module path

• By providing the module name as a string

• By calling the module directly

• By using an import statement

What is a common practice when naming variables for loaded modules?

• Follow a common convention

• Use special characters

• Use random names

• Use numbers

Why is it important to practice coding challenges during the course?

• To memorize code

• To gain real-world experience

• To increase typing speed

• To learn new programming languages

What should you do if you get stuck on a coding challenge?

• Ignore the problem

• Skip the challenge

• Download the lecture resources

• Ask a friend to do it

What is the benefit of using the common variable name for modules?

• It makes the code run faster

• It helps in understanding the code across projects

• It allows for more modules to be loaded

• It reduces memory usage
