Example usage
function poll(fn, validate, interval, maxAttempts) {
let attempts = 0;
return new Promise((resolve, reject) => {
function execute() {
fn().then(val => {
attempts++;
if (validate(val)) resolve(val);
else if (attempts >= maxAttempts) reject(new Error('Max attempts reached'));
else setTimeout(execute, interval);
}).catch(reject);
}
execute();
});
}
// Example placeholder (actual usage requires endpoint)
// poll(() => Promise.resolve({ ok: true }), res => res.ok, 100, 3);05
