Deno.js vs Node.js all the differences you need to know
What is Deno.js?
Deno also supports Native Web Apps (NWA), which are similar to Native Desktop Apps but written in HTML5 instead of C++ etc… HTML5 files are handled by deno-native or webpack-web app, depending on the device.
Code language: JSON / JSON with Comments (json)
console.log("hello, world! via Deno.js");
What exactly is Node.js?
Node also has features like HTTP support and server modules that make it easy to make fast, scalable applications.
console.log("hello, world! via Node.js");
Deno.js vs Node.js
|Deno.js uses V8.||Node.js uses V8’s embeddable engine, WebKit, or Chromium.|
|Deno.js is a powerful tool for creating single-page apps with real-time data without having to write any backend code!||Node.js uses an event loop to execute scripts asynchronously.|
|It does this using WebSockets and SocketIO, which allow your web app to immediately update when new data comes in from your API’s response—no more polling or refreshing required!||It can handle how users interact with the app or work in the background by using modules to implement business logic without reloading this code every time a browser (or mobile device) requests.|
Pros and cons of Deno.js
- Deno.js is free and open source, which means you can use it for free and doesn’t have any license fees to pay.
The biggest problem with Deno.js is that it only has one development environment. This means that many developers will need help debugging and using the tools for development.
Pros and cons of Node.js
- Additionally, js has a thriving community of highly active developers on Stack Overflow, so you can always ask questions there if you get stuck.
- The Node ecosystem is experiencing significant growth as more companies adopt Node to build real-time applications on the web.
- First, more support for other languages and platforms must be needed.
- Developers who use Objective-C or Java may find Node challenging because of the need for more support for these languages.
- Slow response time, low popularity, and fewer standard developers prefer it over other similar languages like PHP.
Application of Node.js and Deno.js
Node.js uses the CommonJS module system, which is widely supported and well-established but can be cumbersome. Deno uses the ECMAScript module system, which is more modern and concise but less widely supported.
When to use each runtime depends on your application’s needs and limitations. If you need a runtime that is easy to use and allows you to get started quickly, Node.js may be a good choice. Deno may be a better choice if you need a more secure runtime that is more difficult to attack. Deno is also a good choice if you are working on a project using TypeScript because it is designed to support TypeScript natively.
Deno.js and Node.js share some similarities, but they also have some significant differences. As we have seen in this Deno.js vs Node.js review, the benefits both offer are vast in different ways: whether high-production use or speed, you are sure to find something you will like about both. The choice is ultimately yours as to which one you want to give a try.
