How to execute 1000 times one synchronous function in parallel in NodeJS?

Question

Node.js

I have one function, it is quite heavy (there may be a loop within a loop, etc.), the execution speed can vary from 10 s - 1 minute, as a result, I need to collect the output of this function together
// fn.js

module.exports = () => {
 // high operation
 console.log("time result", t);
}

// main.js

const fn = require("./fn.js");

// нужно выполнить эту функцию 1000 раз параллельно

How to achieve parallelism in NodeJS?

Answer 1

No way - the node works in one thread. Cut the function into pieces, and run in parts (itself, some wq or promises)
