Reactive triggers

Good use cases for reactive triggers.

• expensive or time-consuming process: Instead of automatically recalculating data whenever an input changes, you might want to let users decide when to update an expensive or time‐consuming computation (e.g., querying an external API). A reactive trigger lets you decouple the immediate input change from the computation, giving the user control over when the data is refreshed.
• Batch Updating: In scenarios where several inputs might change in quick succession, you may not want each change to individually trigger a recalculation. Instead, you can wait until all inputs are set (perhaps with a "Submit" or "Apply Changes" button) and then use a reactive trigger to perform a single, coordinated update.
• Conditional Recalculation: update only under certain conditions. Using a trigger lets you isolate the reactivity to those conditions rather than having it automatically tied to every related input.
• Periodic or Scheduled Updates: You can
