Will JavaScript containers overtake Linux containers?

Developers of the Deno JavaScript and TypeScript runtime are exploring the possibility of JavaScript containers—and the JavaScript sandbox itself—as a higher-level alternative to Linux containers.

In a blog post this week, Ryan Dahl, who spearheaded development of both the Deno and Node.js JavaScript runtimes, cited JavaScript as the “universal scripting language.”

Dahl also noted that Docker popularized the use of Linux containers, with operating system-level virtualization for distributing server software. Each container image is a dependency-free, ready-to-run software package. But browser JavaScript offers a similar hermetic environment at a higher level of abstraction, he said.
