What is the process for executing JavaScript in a secondary thread in V8?

In the v8 engine, JavaScript code is only able to run in the main thread. My goal is to run JavaScript code in a non-main thread so that CPU-intensive tasks cannot interrupt the CPU time of the main thread. However, I am currently at a loss on how to accomplish this.

For this question, I have removed the node.js tag as I am not interested in utilizing multicore capabilities in node.js. Instead, I am working on implementing threads using the native v8 API. Please refrain from providing solutions related to node.js and instead focus on guiding me based on the v8's C++ API.

The following link explains why V8 code cannot be used in a non-main thread; only native C++ code can be executed in user-defined threads. Is there no solution to this limitation?

There is no need to go down to a lower level. Node has advanced enough to offer higher-level options for tasks like these.

You can utilize the child_process module to spawn a separate process with child_process.fork(). This allows your CPU-intensive synchronous tasks to run simultaneously without impacting the main process.

If you're looking to incorporate multiple processes as a standard feature in your application, then the cluster module is what you should use. The cluster module from node core enables users to leverage multi-core systems by running multiple node processes and distributing work among them. It simplifies the technical aspects for you and makes implementation quite straightforward. Take a look at some examples in the documentation.
