// This code is to be used with https://turbo.hotwire.dev. By default Turbo keeps visited pages in its cache 
// so that when you visit one of those pages again, Turbo will fetch the copy from cache first and present that to the user, then 
// it will fetch the updated page from the server and replace the preview. This makes for a much more responsive navigation 
// between pages. We can improve this further with the code in this file. It enables automatic prefetching of a page when you
// hover with the mouse on a link or touch it on a mobile device. There is a delay between the mouseover event and the click
// event, so with this trick the page is already being fetched before the click happens, speeding up also the first 
// view of a page not yet in cache. When the page has been prefetched it is then added to Turbo's cache so it's available for
// the next visit during the same session. Turbo's default behavior plus this trick make for much more responsive UIs (non SPA).

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

# Thee will be more information here when I share the entire problem space I'm working on, but
# in short, this is preview material for my second talk in a series called "What Computer Scientists Know".
# The first talk is on recursion, and goes through several examples., leading up to a problem based
# on a simple puzzle that initial estimates based on performance of a previous puzzle would take years
# to solve on modern computers with the techniques shown in Ruby. That sets the stage for improving the
# performance of that problem with threading, concurrency, and related tuning.
#
# The second talk is on threading and concurrency, touching on algorithmic performance as well.
# Using some knowledge of the problem (board symmetry, illegal moves, etc), we reduce the problem space
# to about .5% of what we initially thought it was.  Still, the initial single threaded solution took more
