⚡ Asynchronous version of `Array.prototype.reduce`.
⚠️
Unlike other async array methods, this runs sequentially because each step depends on the previous result.
Syntax
import { reduceAsync } from '@opentf/std';
reduceAsync<T, R>(
arr: T[],
cb: (acc: R, value: T, index: number) => Promise<R>,
initialValue: R
): Promise<R>;Parameters
arr: The array to iterate over.cb: An async callback function (accumulator, value, index).initialValue: The initial value of the accumulator.
Returns
A Promise that resolves to the final accumulated value.
Examples
const items = [1, 2, 3];
const sum = await reduceAsync(items, async (acc, n) => {
return acc + n;
}, 0); //=> 6
