Why Learn Node.js?

Node.js has become one of the most popular technologies in modern web development. Built on Google Chrome’s V8 JavaScript engine, it allows developers to run JavaScript on the server side, breaking the traditional barrier where JavaScript was confined only to the browser.

Here are a few reasons why Node.js is worth learning

High Performance: Its event-driven, non-blocking I/O model makes it ideal for handling thousands of requests simultaneously.
Global Adoption: Tech giants like Netflix, LinkedIn, PayPal, and Uber use Node.js to power their large scale, real time applications.
Full-Stack JavaScript: With Node.js, you can use one language (JavaScript) for both frontend and backend development.
Massive Ecosystem: Node Package Manager (NPM) provides access to millions of reusable libraries to speed up development.

With its scalability, speed, and efficiency Node.js is a must have skill for developers aiming to build modern, high performance applications.

Prerequisites to Get Started

Before diving into Node.js development, it’s helpful to have a solid understanding of a few basics:

Programming Fundamentals: Comfort with variables, loops, functions, and conditional statements.
JavaScript Basics: Understanding of ES6+ features such as arrow functions, promises, async/await, and modules.
Asynchronous Programming: Familiarity with callbacks, events, and handling multiple tasks concurrently.
Basic Understanding of Databases: Knowing how relational (SQL) or NoSQL databases work will help when building data-driven apps.
