Deno is a free and open source JavaScript runtime built on Google’s V8 engine, Rust, and Tokio. The project was announced by Ryan Dahl in 2018 with the goal of addressing shortcomings of Node.js, which Ryan also created. Since then, the Deno project has grown tremendously in popularity, and they recently announced Deno KV which is a database built into Deno.

Luca Casonato is a Software Engineer on the Deno project and joins the show to talk about Deno’s design, its new database, and the future of the JavaScript ecosystem.
