The new Hologram.JS module provides a comprehensive API including js_import, JS.call, JS.get/set/delete, JS.new, JS.eval, and JS.dispatch_event. JavaScript Promises are mapped to Elixir Tasks, enabling async operations with Task.await/1. The release also adds Web Components template support, fixes language server recompilation loops (covering ElixirLS, Lexical, and Next LS), and refactors the Unicode module. A breaking change requires explicit use Hologram.JS in modules that use the ~JS sigil. The JS interop PR alone added over 7,000 lines across 150 files. ## Full article daily.dev links to this article rather than hosting it.
