* Egendefinert hook for å toggle funksjonalitet av og på ved å sette boolske-flagg i browser-storage. | ||

* @param {string} [key='storagetoggle'] - Nøkkelen som brukes til å lagre utviklingsmodus-flagget. | ||
* @param {Storage} [storageArea=localStorage] - Storage-området som brukes til å lagre utviklingsmodus-flagget, | ||

* Denne hooken lytter etter endringer for den spesifiserte storage-nøkkelen og oppdaterer tilstanden deretter. | ||

* const isDevMode = useStorageToggle({ key: 'devmode' }); | ||
* if (isDevMode) { | ||
* // Utfør handlinger som er spesifikke for utviklingsmodus | ||
