I have the above code for endlessly scrolling a page in endless mode. But somehow it seems to stops before. References-https://stackoverflow.com/a/31058403/3646408
Edit 1:
$ phantomjs --version
2.1.1
On runnning @alexce code it showed different output in 2 runs, the date check makes it clear that there are more tweets:
