In the previous tutorial series, Mytour has shared with you some information about Basic Guides to Java Language. In this tutorial series, Mytour will continue to share with you useful information to get familiar with and learn Node.js more effectively.
Learning Node.js
Fundamentally, Node.js is an independent platform built on the V8 Engine, a JavaScript library integrated into Chrome, and used to develop deep I/O web applications such as live video streaming pages, single-page applications (SPAs), and other web applications.
As mentioned above, Node.js is completely free and open-source software, chosen by thousands of developers worldwide.
Why Learn Node.js?
Node.js employs an asynchronous programming language.
The general task for web servers is to open files on the server and return the content to the client applications.
Here's how PHP and ASP handle file requests:
1. Send tasks to the computer's file system.
2. Wait while the file system opens and reads files.
3. Return content to the client.
4. Be ready to handle the next request.
Here's how Node.js handles file requests:
1. Send tasks to the computer's file system.
2. Be ready to handle the next request.
3. While the file system opens and reads files, the server returns content to client applications.
Node.js doesn't need to wait and moves on to the next requests.
Additionally, Node.js handles multiple connections with just a single-threaded, leveraging non-blocking mechanism, asynchronous programming which is extremely efficient without consuming much RAM.
Advantages of Node.js
Here are some advantages of Node.js:
- Node.js can create dynamic content pages.
- It can create, open, read, write, delete, and close files on the server.
- Collect form data.
- Additionally, Node.js can add, delete, modify data in the database.
What is a Node.js File?
- A Node.js file contains tasks executed on specific events. A typical event is when a user tries to access a port on the server.
- Node.js files must be initialized on the server before any application effects.
- Node.js files have the file extension '.js'.
In the above article, Mytour has just shared with you some of the most basic information about Node.js. To learn Node.js more effectively, it's best to have a basic understanding of JavaScript. Additionally, because developing web applications using Node.js, it would be beneficial if you already have a foundation in web technologies such as HTML, CSS, AJAX, ... .
In the following articles, Mytour will delve into introducing Node.js in detail, how to install Node.js, ...
