Node.js Built-in Modules Part 3

Welcome to the third part of our Node.js tutorial series on built-in modules. In this article, we will explore more of the core modules that come pre-installed with Node.js, and how you can use them in your applications.

Child Process Module

The Child Process module allows you to spawn child processes in Node.js. This can be useful if you need to run external commands or scripts from your Node.js application. You can create new child processes using the `child_process.spawn()` method, which takes the command to run as an argument.

Cluster Module

The Cluster module allows you to create a cluster of Node.js processes to take advantage of multi-core systems. This can help improve the performance and scalability of your Node.js applications. You can use the `cluster.fork()` method to create new worker processes that share the same port as the master process.

Assert Module

The Assert module provides a set of assertion functions that can be used for testing and debugging your Node.js applications. These functions allow you to check if values meet certain conditions and throw errors if they don’t. The most commonly used function is `assert.equal()`, which compares two values for strict equality.

Conclusion

These are just a few more of the built-in modules that Node.js provides to help you build powerful and efficient applications. By familiarizing yourself with these modules and their functionalities, you can take your Node.js skills to the next level.
