Menyimpan data di browser yang persisten (tidak hilang saat tab ditutup).
localStorage.setItem(key, value)localStorage.getItem(key)localStorage.removeItem(key)localStorage.clear()Note: Hanya menyimpan string. Untuk object/array, gunakan JSON.stringify/parse.
Sama seperti localStorage, tapi data hilang saat tab ditutup.
function saveName() {
const name = document.getElementById('nameIn').value;
localStorage.setItem('userName', name);
document.getElementById('lsOutput').textContent = '✅ Saved: "'+name+'"';
}
function loadName() {
const name = localStorage.getItem('userName');
document.getElementById('lsOutput').textContent = name ? '📦 Loaded: "'+name+'"' : '⚠️ No data found';
}
function clearName() {
localStorage.removeItem('userName');
document.getElementById('lsOutput').textContent = '🗑️ Cleared!';
}
