lazy javascript that you can use to tell the browser
to keep scrolling down as you write content. This is
handy if you said don't cache, and your web server
is set up to not compress the returned data to browser.
for example you want to write a UI that you upload a .csv
file to, and you have to do things with the data, and you
have implemented a loging system that writes to a file and
stdout at the same time, you could display your logs real
time back to a browser as you process the .csv file.
