The average page loads 15–25 third-party requests, accounting for 60–80% of total page weight. Data from the HTTP Archive confirms that third-party JavaScript is growing faster than first-party code. Each external script adds network latency, parse and compile time, main-thread contention, and potential security risks. The good news: you can optimize third-party scripts without removing their functionality. The goal is to minimize performance impact while preserving business value.</p>
