    (description "Propshaft is an asset pipeline library for Rails.  It's
built for an era where bundling assets to save on HTTP connections is no
longer urgent, where JavaScript and CSS are either compiled by dedicated
Node.js bundlers or served directly to the browsers, and where increases in
bandwidth have made the need for minification less pressing.  These factors
allow for a dramatically simpler and faster asset pipeline compared to
previous options, like Sprockets.")

to write any JavaScript.  Turbo accelerates links and form submissions without
requiring server-side changes to the generated HTML.  It allows carving up a
page into independent frames, which can be lazy-loaded and operated as
independent components.  Finally, it helps making partial page updates using
just HTML and a set of CRUD-like container tags.  These three techniques
reduce the amount of custom JavaScript that many web applications need to
write by an order of magnitude.  And for the few dynamic bits that are left,
Stimulus can be used.")
