Bun, Deno, Node js: Recreating a JavaScript runtime from Scratch by Erick Wendel

In a recent talk, developer Erick Wendel discussed the process of recreating a JavaScript runtime from scratch. He highlighted the importance of understanding the inner workings of popular runtimes like Node.js, Deno, and Bun in order to improve performance and efficiency.

Node.js

Node.js is a popular JavaScript runtime built on the V8 JavaScript engine. It allows developers to run JavaScript code outside of a browser, making it ideal for server-side applications. By understanding how Node.js works under the hood, developers can optimize their code for better performance.

Deno

Deno is a secure runtime for JavaScript and TypeScript built on the Rust programming language. It aims to provide a more secure and efficient environment for running JavaScript code. By understanding how Deno handles security and resource management, developers can build more robust applications.

Bun

Bun is a new JavaScript runtime designed for fast and efficient performance. It is optimized for running JavaScript code in a browser environment. By understanding how Bun manages resources and handles runtime tasks, developers can build faster and more responsive web applications.

In conclusion, understanding the inner workings of JavaScript runtimes like Node.js, Deno, and Bun is essential for building efficient and performant applications. By studying how these runtimes handle memory management, security, and performance optimization, developers can improve their coding skills and create better software.
