Yоu receive webhооk events from а messаging provider. Duplicаtes happen. Implement dedupeEvents() to keep only the first/earliest occurrence of each event based on a stable key. Requirements Create a stable key for each event: key = messageId + ":" + type + ":" + recipient Cleaning rules messageId and recipient: if missing or empty/whitespace → "unknown" type: trim + lowercase; if missing/empty → "unknown" ts: if missing or not a finite number → Date.now() Deduping rules If multiple events share the same key, keep the event with the earliest ts Output Return the deduped list sorted by ts ascending Output should be an array of CleanEvent Starter Code TypeScript type ProviderEvent = { messageId?: string; type?: string; // not guaranteed to be normalized recipient?: string; ts?: number; // epoch ms; may be missing }; type CleanEvent = { messageId: string; type: string; recipient: string; ts: number; }; function cleanStr(v?: string): string { const t = (v ?? "").trim(); return t.length ? t : "unknown"; } function cleanType(v?: string): string { const t = (v ?? "").trim().toLowerCase(); return t.length ? t : "unknown"; } function cleanTs(v?: number): number { return Number.isFinite(v) ? (v as number) : Date.now(); } /** * Dedupe by messageId:type:recipient (after cleaning). * For duplicates, keep the earliest ts. * Return sorted by ts ascending. */ export function dedupeEvents(events: ProviderEvent[]): CleanEvent[] { // TODO return []; } // Example input const input: ProviderEvent[] = [ { messageId: "m1", type: "DELIVERED", recipient: "a@x.com", ts: 1000 }, { messageId: "m1", type: "delivered", recipient: "a@x.com", ts: 900 }, // duplicate, earlier { messageId: "m2", type: "opened", recipient: "b@x.com", ts: 1100 }, { messageId: "m2", type: "opened", recipient: "b@x.com", ts: 1200 }, // duplicate, later ];
