method Domain.prototype.run
Usage in Deno
```typescript import { Domain } from "node:node__domain.d.ts"; ```
Domain.prototype.run<T>(fn: (...args: any[]) => T,...args: any[],): T
Run the supplied function in the context of the domain, implicitly
binding all event emitters, timers, and low-level requests that are
created in that context. Optionally, arguments can be passed to
the function.
This is the most basic way to use a domain.
```js
import domain from 'node:domain';
import fs from 'node:fs';
const d = domain.create();
d.on('error', (er) => {
console.error('Caught error!', er);
});
d.run(() => {
process.nextTick(() => {
setTimeout(() => { // Simulating some various async stuff
fs.open('non-existent file', 'r', (er, fd) => {
if (er) throw er;
// proceed...
});
}, 100);
});
});
```
In this example, the `d.on('error')` handler will be triggered, rather
than crashing the program.
