Function resolveFields

Returns a copy of object, with the same properties. For each property that has a basic value (string, number, boolean, object), the value is set for the return object. If the property is a function or generator, its value is used instead. Async functions and generators are also usable.

Use resolveFieldsSync for a synchronous version.

Not recursive.

In the below example, the function for the property random is invoked.

const state = {
 length: 10,
 random: () => Math.random();
}
const x = resolveFields(state);
// { length: 10, random: 0.1235 }
Copy

It also works with generators

import { count } from './numbers.js';

const state = {
 length: 10,
 index: count(2) // Generator that yields: 0, 1 and then ends
}
resolveFields(state); // { length: 10, index: 0 }
resolveFields(state); // { length: 10, index: 1 }
// Generator finishes after counting twice:
resolveFields(state); // { length: 10, index: undefined }
Copy
