Here is a comprehensive guide to understanding, building, and optimizing Java addons for the V8 engine. Why Connect Java and V8? // Access the object from JavaScript String jsCode

Supports both V8 and Node.js mode; built-in support for asynchronous calls; actively maintained; supports tracking of memory leaks.

对于今天的Java开发者而言，选择的答案取决于具体场景： Supports both V8 and Node

V8运行时核心是单线程模型。对于高并发场景，可采用多运行时池（如Javet内置的V8运行时池），每个运行时绑定一个独立线程，将不同JS任务分配到不同运行时执行，以充分利用多核。

For new projects, utilize Javet or investigate GraalVM before committing to the older J2V8 library, ensuring long-term support and compatibility.
