A JavaScript shortcut for extracting values from objects and arrays into individual variables.
Destructuring is a JavaScript syntax that lets you unpack values from arrays and objects into distinct variables in one line. Instead of writing const name = user.name; const email = user.email;, you write const { name, email } = user;.
Array destructuring uses position: const [first, second] = myArray;. Object destructuring uses key names: const { data, error } = await supabase.from('posts').select();. You'll see this Supabase pattern constantly.
Destructuring is everywhere in modern React: extracting props, unpacking state from useState (const [count, setCount] = useState(0)), and getting data from API responses. Claude Code uses destructuring extensively in generated code.
