Building a React Hook for Session Storage Form Persistence

Short summary

A technical tutorial on building a custom React hook (useSessionPersistedState) that mirrors form input data into window.sessionStorage, protecting users from data loss on accidental tab closure or browser crashes. The hook initializes from cached state and syncs changes automatically, clearing only on successful form submission. Includes full code examples for the hook and a sample resilient audit form component.
