: Speed is calculated as Distance (File Size) / Time . To avoid cached results, a "cache-buster" (a random query parameter) is added to the URL. Implementation Steps :
: A built-in, readable way to track how long a block of code takes to execute. This is useful for quick debugging. 3. Key Considerations & Pitfalls
If you want to measure how fast your own JavaScript functions run, use the Performance API rather than the standard Date object.
: Use performance.now() for sub-millisecond precision. Fetch the Resource : Use the Fetch API to download the file. End the Timer : Record the time immediately upon completion.
: This returns a high-resolution timestamp in milliseconds, accurate to five-thousandths of a millisecond. javascript
