I wasn't able to find the answer to your question in the official Deno documentation. However, in general JavaScript, there isn't a direct way to check if a promise has been resolved without altering its state or using additional variables. Typically, you would handle a promise's resolution with .then() and .catch() methods or by using async/await syntax. If you need to keep track of whether a promise has been resolved, you might consider using a variable to flag the resolution status. Here's a simple example:
let isResolved = false;

const myPromise = new Promise((resolve, reject) => {
// Simulate some asynchronous operation
setTimeout(() => {
resolve('Promise resolved');
}, 1000);
});

myPromise.then((value) => {
isResolved = true;
console.log(value);
});

// Later in your code, you can check the isResolved flag
// to see if the promise has been resolved.
let isResolved = false;

const myPromise = new Promise((resolve, reject) => {
// Simulate some asynchronous operation
setTimeout(() => {
resolve('Promise resolved');
}, 1000);
});

myPromise.then((value) => {
isResolved = true;
console.log(value);
});

// Later in your code, you can check the isResolved flag
// to see if the promise has been resolved.
Please note that this advice is not based on the Deno documentation, and you should double-check the accuracy of this advice. If you're working within the context of Deno and need Deno-specific functionality, you may want to explore Deno's standard library or third-party modules that could provide additional utilities for working with promises.
