## Introduction:
In this blog post, I want to remind myself why I decided to learn NestJS. As a developer who wants to create strong, reliable, and expandable server-side applications using TypeScript, NestJS caught my attention as a good recommendation. Let's explore the reasons that make NestJS worth the time and effort.

## Understanding NestJS Compared to React and Angular:
To understand what NestJS is all about, it's important to compare it with React and Angular, which are frameworks used for front-end development. React is known for its flexibility and freedom to create user interfaces, mainly for the client-side. On the other hand, Angular takes a comprehensive approach, providing stability and reliability for building web applications.

## The Role of NestJS on the Server-Side:
While React is great for the front-end, the server-side requires a different way of doing things. NestJS comes in as the perfect solution, offering a framework that meets the server's need for security and strength.

## What is NestJS, and Why Should I Learn It?
NestJS is a powerful framework designed to build efficient and expandable server-side applications using TypeScript. Inspired by Angular, NestJS follows the principles of organizing code, writing clean and structured code, and managing dependencies. TypeScript's strong typing and robust features make it the main language for NestJS.

## Exploring the Advantages of NestJS:
When it comes to back-end development, the focus is more on data and logic rather than user experience. NestJS excels in this area with its structured approach, influenced by Angular. This strong foundation allows NestJS to offer many features for organizing code effectively, including modular architecture, data manipulation through pipes, and the use of controllers.

## A Wide Range of Built-in Features:
NestJS doesn't just offer a structured approach; it goes above and beyond by providing a wide range of built-in features. These include task scheduling, queue management, logging, cookie handling, validation, and much more. Additionally, the framework seamlessly integrates WebSockets, which allows real-time communication in applications like chat or multiplayer games. Another great advantage is that NestJS supports both REST and GraphQL APIs, giving developers the flexibility to choose the best option for their project.

## NestJS vs. Other Node.js Frameworks:
Compared to other Node.js frameworks like Express.js, NestJS stands out with its comprehensive set of features, structured approach, and strength. Unlike React or Express, which may require additional libraries for certain features, NestJS offers a complete solution, reducing the need to search for external dependencies. However, it's important to note that NestJS's extensive capabilities come with a steeper learning curve and may feel overwhelming for smaller projects.

## The True Value of Learning NestJS:
So, why should I invest my time in learning NestJS? The steep learning curve is actually one of the main reasons why NestJS is worth the effort. It's not just about learning a specific syntax, but also understanding the best practices of back-end development integrated into a framework. This knowledge becomes a valuable asset, even if I decide to work with a different framework or programming language later on. When I invest time in learning NestJS, I am ultimately investing in my own growth as a developer.

## Conclusion:
NestJS is a powerful and valuable choice for building server-side applications. Its foundation inspired by Angular, extensive features, and structured approach make it an excellent option for developers looking for strong and expandable solutions. As I continue my journey in the ever-changing world of development, learning NestJS proves to be a valuable investment in advancing my skills and expertise. So, let's embrace NestJS and unlock its full potential to shape a brighter future in server-side development!
