VDOM doesn't make things fast

Read Original

This technical article critically examines the performance implications of React's Virtual DOM (VDOM), arguing that the VDOM's diffing process isn't always the fastest approach. It explains how DOM operations compare to VDOM overhead and contrasts React with modern, non-VDOM frameworks like Lit, Svelte, and SolidJS. Using Lit as a primary example, it details how tagged template literals enable efficient, targeted DOM updates without a virtual representation, highlighting the runtime and bundle size benefits of the non-VDOM approach.
