So, I don't know in which condition, we need to manually get records and its length will not be 0.
The takeRecords()
method will usually return no entries, but in some cases it can happen (e.g. if takeRecords()
is called in the same frame where a new LCP candidate has been discovered—but since the callback is run async, it hasn't been invoked yet).
The point of calling it in the line you referenced is to just make sure there aren't any pending entries prior to reporting the value.
