Bun aims to “run most of the world's JavaScript outside of browsers, bringing performance and complexity enhancements to your future infrastructure, as well as developer productivity through better, simpler tooling,” Sumner said in a YouTube interview.

The New Stack is a publication covering trends and technologies in cloud-native development, DevOps, and software delivery. Developers can learn about containerization, Kubernetes, and cloud computing, as well as explore topics such as microservices architecture, serverless computing, and continuous integration/continuous delivery (CI/CD) pipelines.

Bun is a drop-in replacement for running JavaScript and Typescript applications. It was designed to be an all-in-one tool for bundling, transpiling, and running code at lightning speed. It processes about three times more HTTP requests per second than Node.js when rendering React server-side.
