Node.js is a powerful, event-driven runtime environment built on Chrome's V8 JavaScript engine. One of its core components is the EventEmitter class, which is fundamental to how Node.js applications handle asynchronous events. In this article, we'll delve into what the EventEmitter is, its advantages and disadvantages, and provide a real-world example of how to use it.

What is EventEmitter?​

The EventEmitter class is part of the Node.js events module and provides a way to handle asynchronous events. It allows objects to emit events and other objects to listen for those events and execute callbacks when they occur. This pattern is essential for building non-blocking, event-driven applications.

REST API naming conventions are essential for creating readable, understandable, and maintainable APIs. Following standard naming conventions helps ensure consistency and predictability, making it easier for developers to work with the API. Here are some best practices and examples for REST API naming conventions:

Creating REST APIs involves more than just following naming conventions; it includes adhering to a set of best practices and guidelines to ensure the API is robust, maintainable, and scalable. Here are some best standards and guidelines for REST API development:

1. Design for Consumer Needs​

Understand and design the API around the needs of the clients that will consume it. This includes providing clear and precise documentation.

What’s New in Angular 18?​

Angular 18 brings significant innovations in state management, data handling, and application logic flow. This latest version reduces state complexity, enhances performance, and provides better tools for developers to manage and maintain their applications. Here are the key features introduced in Angular 18:

Overview​

Angular applications often require the efficient management of component loading to enhance performance and user experience. One effective technique for achieving this is by using deferrable views, also known as @defer blocks. Deferrable views allow developers to defer the loading of select dependencies within a component template, such as components, directives, pipes, and associated CSS. By wrapping a section of your template in a @defer block, you can specify the conditions under which these dependencies should be loaded, significantly improving the initial load time and overall performance of your application.

In the world of software development, writing clean, readable, and maintainable code is crucial. Uncle Bob’s book, “Clean Code,” provides a comprehensive guide on how developers, especially those less experienced, can achieve this. Below are some key principles and rules from the book, along with examples to illustrate how they can be implemented.

What is Freelancing?​

Freelancing refers to the practice of individuals offering their skills and services to clients on a project or contract basis, rather than working as employees for a single employer. Freelancers operate as independent contractors, and they can work for multiple clients simultaneously. Freelancing provides flexibility in terms of work hours, location, and the types of projects undertaken.
