在示例中，通过Task.Run方法创建一个任务，该任务调用CalculateSum方法来计算从1到10的和。主线程继续执行并输出"Main thread"，然后等待任务完成并获取结果（使用task.Result）。最后，输出计算结果并输出"Main thread exiting"。Parallel Parallel是一个并行编程库，提供了一种简化并行处理的方式，如并行循环、迭代和任...

这里的临时 emscripten::val 对象会析构,进而减少 handle 的在句柄表中的引用计数。(如果句柄的引用计数归零,则对应 JavaScript 对象被句柄表释放引用,若无其他可达引用,则该对象可被 JavaScript 的 GC 回收。)在 C# 侧,我们使用 P/Invoke 来调用这个函数。
