This pull request significantly enhances the documentation for the
createSubscriber
function, a crucial but under-documented part of Svelte 5's reactivity system. Key improvements include:Clearer Opening Description: Rewritten in natural language to immediately explain
createSubscriber
as a "bridge" between external events and Svelte's reactivity.Comprehensive Examples: Added three detailed examples demonstrating common patterns: a generic reactive utility, a class-based
MediaQuery
integration, and a function-basedmousePosition
tracker. These highlight proper Svelte 5 patterns and essential cleanup.Improved JSDoc Structure: Enhanced with clear
@param
tags, multiple@example
sections, a dedicated "Implementation Details" section, and a practical "When to use" guide.This enhancement makes
createSubscriber
more intuitive and helps developers confidently integrate external APIs, ensuring proper usage to prevent issues such as memory leaks. Hopefully, we can further clarify one of Svelte 5's powerful features!
