function getProperty<K, V>(record: ReadonlyRecord<K, V>, key: K): V | undefined;

Defined in: packages/common/src/Object.ts:214

Safely gets a property from a record, returning undefined if the key doesn't exist.

TypeScript's Record<K, V> type assumes all keys exist, but at runtime accessing a non-existent key returns undefined. This helper provides proper typing for that case without needing a type assertion.

Example

const users: Record<string, User> = { alice: { name: "Alice" } };
const user = getProperty(users, "bob"); // User | undefined
