About the publication

JTypes

Practical JavaScript and TypeScript tools, with notes on what they can and cannot tell you. Start with a JSON sample.

Our focus

We publish practical material about typescript, json and apis, javascript fundamentals. Each guide should leave you with something you can check, try or make.

The tool on our home page works in your browser. It does not upload your inputs. Read its limits alongside the output, especially before using a result in a live project.

An independent project

This is a new project using the jtypes.com domain. It does not represent the previous website, its owners or their services. Our articles and tools are original work.
