In plain words
JSONP is a developer tool that enables cross-domain requests to JSON APIs using AJAX.

The tool is designed for web developers who need to integrate third-party JSON data into their applications across different domains.

But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
