Javet is Java + V8 (JAVa + V + EighT). It is an awesome way of embedding Node.js and V8 in Java.

If you like my work, please Star this project. And, you may follow me @sjtucaocao, or visit https://blog.caoccao.com/ or https://caoccao.blogspot.com/. And the official support channel is at discord.

? If you like my work, please donate to support me. If you have a retired Mac OS (x86_64) device and are fine with mailing it to me, that will be great because I don't have such device to support the community. Thank you for supporting Javet.
