Why Use Node.js and Nest.js

Now that you understand what the backend does, the next question is: how do you actually build it?
Backend code needs an environment where it can run. This is where Node.js comes in. Node.js allows us to run JavaScript on the server, handle requests, process logic, and send responses.
But writing everything directly with Node.js can quickly become messy as your project grows. You would have to organize files, structure your code, and solve common problems on your own.
This is where Nest.js helps.
Nest.js is a framework built on top of Node.js that gives your application a clear structure. It helps you organize code into modules, separate logic, and follow a consistent architecture. Instead of figuring everything out from scratch, you work with a system that is already designed for building scalable backends.
In this track, you will learn how to build backend features using Node.js and Nest.js.
However, you can't jump into Nest.js right away.
Node.js runs JavaScript, so before working with backend tools, you need to understand the language itself. You need to know how to write code, work with data, and control program behavior.
That's why the next step is JavaScript.
You will start with the fundamentals, and then use that knowledge to move into Node.js and finally Nest.js.
