Ryan Dahl and his team do not cease to amaze the development community with new ideas. For several years of the active development process, the Deno runtime has evolved from a promising project to a viable alternative to Node.js for many projects.

Now, it is time to unveil a new initiative of the Deno team called JSR. It is a new package registry for modern JavaScript and TypeScript. 

According to the project’s website, JSR is not a replacement for npm, but it’s superset that can be used with any JS package manager and in popular runtimes (Node, Deno, Bun, etc.).
