/**
 * Starts a promise with an asynchronous function that has retry tolerance.
 *
 * @param {AsyncFunction<T> | Promise<T>} asyncFunction
 * - An asynchronous function that will be called, returning a result in a promise.
 * @param {number} [count=3]
 * - A positive integer between 0 and 30 indicating the number of retries.
 * @param {number} [delay=100]
 * - The time in milliseconds to wait between retries.
 *
 * @return {RetryFunction<T>}
 * The function wrapper of return the result within a promise after retries.
 *
 * @example
 * Promise.resolve().then(retry(asyncFunction, 5, 1000));
 * Promise.resolve().then(retry(() => asyncFunction(1, 2), 5, 1000));
 * Promise.resolve().then(retry(promise, 5, 1000));
 * // Retry 5 times with a 1-second interval.
