Deno vs. Node.js is the latest subject for debate since a new version of Deno 1.0 has been published and is currently generating a buzz. Deno JavaScript supports addressing all of the inherent node problems. Ryan Dahl- is the creator of both Node.Js and Deno. Node.js is a fast and reliable full-stack framework with its ecosystem and is a great server. Deno is a secure JavaScript, which simultaneously compiles JavaScript and Typescript code.

Ryan Dahl also admitted the development of Node. Js should have more security, modules, and dependencies, and that both runtime and package managers should be in one executable instead of the package management program.

Main Features of Deno

Deno is a reliable JavaScript and Typescript, which is based on the V8 JavaScript engine for JavaScript.

• Deno’s core is written in Rust
• Deno principle – Tokio loop is written in Rust
• Supports both JavaScript and Typescript
• V8 (Google’s JavaScript runtime used in Chrome and Node)

Advantages of Deno

• By default, it’s a secure runtime environment.
• Well designed security module
• It is built on Rust (vs. C++ for Node)
• Built-in Dependence Controller and Code Developer

Main Comparisons between Node.JS and Deno

• Deno does not use npm and no package.json files to define the dependencies.
• Js was written in C++ while Deno’s core was written in the Rust programming language.
• Node was created in 2009 and a number of new JS features have been introduced, such as Promise, Await, ES modules, Async, Await, etc., which are supported in Deno.
• Deno supports Typescript and has a built-in Typescript compiler for a large application.
• Typescript JavaScript removed the error of the developer prior to the code execution.
• Deno can have a break on unhandled exceptions, which is not possible in Node.Js.
• Deno is more secure than Node Js because it needs explicit permissions for the file, network, and environment access.
• ES6 Import Claims a decentralized approach to regional management.
• Deno is released with a range of pre-loaded tools such as Deno install, Deno data, Deno fetch, Deno code formatting, etc.

Conclusion

Deno is shaping up as an exciting project that has been rising steadily for quite some time now. Node.js has a long way to go, too. Where Deno provides a comprehensive permissions scheme and first-class support for Typescript, Node.Js has a vast and well-established ecosystem around it that has been in service for over a decade.
