batch

Groups multiple signal updates so an effect runs only once after all updates.

import { signal, batch } from '@hellajs/core';

// Create signals for form state
const username = signal('');
const email = signal('');
const isSubmitting = signal(false);
const isSuccess = signal(false);

function submitForm() {
  batch(() => {
    isSubmitting(true);

    // Simulate async form submission
    setTimeout(() => {
      batch(() => {
        isSubmitting(false);
        isSuccess(true);
        username('');
        email('');
      });
    }, 1000);
  });
}
