Deno Course – Better than Node.js?

Deno is a relatively new and emerging runtime environment for JavaScript and TypeScript that aims to improve upon certain aspects of Node.js. Some developers have even claimed that Deno is better than Node.js in terms of performance, security, and ease of use. This course will explore the features and capabilities of Deno and compare it to Node.js, to help you determine whether it might be a better choice for your next project.

We will start by learning the basics of Deno, including how to set up a development environment and how to create a new Deno project. We will learn about the core features of Deno, such as its built-in support for TypeScript, its use of the V8 JavaScript engine, and its use of the Rust-based Tokio library for asynchronous programming. We will also learn about the Deno standard library, which provides a wide range of functionality, including support for HTTP, WebSockets, and more.

Next, we will delve into the differences between Deno and Node.js, focusing on areas such as performance, security, and ease of use. We will learn about the advantages of Deno's built-in support for TypeScript and its use of the V8 JavaScript engine, and how these features can lead to improved performance and security. We will also learn about the differences in the package management and module loading systems between Deno and Node.js, and how these differences can impact ease of use.

After gaining a solid understanding of the features and capabilities of Deno, we will put our knowledge to the test by building a simple web application. We will use the concepts we have learned to create a simple web application that performs a specific task, such as a to-do list application or a weather application, and compare it to a similar application built in Node.js.

Finally, we will explore the current state of the Deno ecosystem and its future potential. We will discuss the current popularity and adoption rate of Deno, and the availability of libraries and frameworks. We will also consider the potential future developments of Deno, and its potential to become a major player in the JavaScript runtime environment market.

By the end of this course, you will have a solid understanding of Deno and its features, and the ability to compare it to Node.js and make an informed decision about whether Deno is a better choice for your next project.
