-/**
- * Calculates the [TTFB](https://web.dev/articles/ttfb) value for the
- * current page and calls the `callback` function once the page has loaded,
- * along with the relevant `navigation` performance entry used to determine the
- * value. The reported value is a `DOMHighResTimeStamp`.
- *
- * Note, this function waits until after the page is loaded to call `callback`
- * in order to ensure all properties of the `navigation` entry are populated.
- * This is useful if you want to report on other metrics exposed by the
- * [Navigation Timing API](https://w3c.github.io/navigation-timing/). For
- * example, the TTFB metric starts from the page's [time
- * origin](https://www.w3.org/TR/hr-time-2/#sec-time-origin), which means it
- * includes time spent on DNS lookup, connection negotiation, network latency,
- * and server processing time.
