Use for questions about various Google APIs. The APIs are usually based on popular Google consumer products, including Cloud Platform, Google Maps, Google Earth, AdSense, Adwords, Google Apps, and YouTube. Do not use for API client library questions.

Hotwire is an alternative approach to building modern web applications without using much JavaScript by sending HTML instead of JSON over the wire.

HTML (HyperText Markup Language) is the markup language for creating web pages and other information to be displayed in a web browser. This tag is rarely used alone and is often paired with [CSS] and [JavaScript].

For questions about programming in ECMAScript (JavaScript/JS) and its different dialects/implementations (except for ActionScript).

jQuery is a popular cross-browser JavaScript library that facilitates Document Object Model (DOM) traversal, event handling, animations and AJAX interactions by minimizing the discrepancies across browsers.

It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams. It also provides pub-sub capabilities.

Turbo Frames decompose pages into independent contexts, which scope navigation and can be lazily loaded

Turbo Streams deliver page changes over WebSocket, SSE or in response to form submissions using just HTML and a set of CRUD-like actions.

XML (Extensible Markup Language) is a structured document format defining text encoding rules. When using this tag include additional tags such as programming language, tool sets, XML technologies being used, and other tags describing the environment of the problem posted. XML flexibility lends to a wide variety of uses for human and machine data transfer so be specific as to tools and libraries.
