between the most popular frontend frameworks (React, Svelte and Solid in particular) what are the features a modern frontend framework must have to be considered a serious option? focus on frontend frameworks with fine grained reactivity. ignore features like server side rendering and server components and focus on frontend features. identify features and requirements that are handled differently in each framework and focus on the problems they solve.
To be considered a serious modern frontend framework with fine-grained reactivity, the following features and capabilities are essential. These features address core challenges like efficient DOM updates, state synchronization, and developer ergonomics. Below is a breakdown of these requirements and how React, Svelte, and Solid handle them differently:
A framework must track dependencies at the most granular level (e.g., individual variables or DOM nodes) to update only what changes, avoiding
