Become a sponsor to Jos de Jong
I'm Jos de Jong, a passionate programmer. In my spare time I love to work on the open source projects jsoneditor and mathjs and some other small projects. I started them long time ago because I needed them myself in my daily life as programmer and engineer. And this is what keeps me motivated: these projects solve an actual need of developers like me, working with JSON data on a daily basis, or working with advanced mathematics in a modern web application. The projects are in good shape, and there is plenty of ideas and improvements just waiting to be implemented.
If you care about jsoneditor or mathjs like I do, please support me via Github Sponsors :)
