▶ The 3 Ways JavaScript Frameworks Render the DOM
SolidJS creator Ryan Carniato explores three primary rendering strategies employed by modern JavaScript frameworks: Virtual DOM (VDOM), fine-grained reactivity, and compiled output. Key Highlights: 1. Virtual DOM (VDOM): Frameworks like React utilize a VDOM to batch updates and reconcile changes efficiently. While this approach simplifies development, it can introduce performance overhead due to the need for diffing and re-rendering entire component trees. 2. Fine-Grained Reactivity: SolidJS adopts a fine-grained reactivity model, where updates are precisely targeted to affected parts of the DOM. This method eliminates the need for a VDOM, resulting in more efficient updates and improved performance. 3. Compiled Output: Frameworks such as Svelte compile templates into optimized JavaScript code during build time. This approach removes the runtime overhead associated with VDOM diffing or reactive tracking, leading to faster execution. Carniato provides visual comparisons and code examples to illustrate how these rendering strategies impact performance, developer experience, and application scalability. The video serves as an insightful overview for developers interested in understanding the trade-offs between different rendering paradigms in JavaScript frameworks.
