This technical blog post explores three reactivity algorithms used in modern web frameworks: push reactivity, pull reactivity, and hybrid push/pull approaches. The author uses spreadsheet analogies to explain core reactivity concepts including efficiency, fine-grained updates, and glitch prevention. The article serves as preparation for building a reactive engine and compares different architectural approaches to dependency tracking.
Background
Reactivity is a fundamental concept in modern web development where UI components automatically update when underlying data changes. Popular frameworks like React, Vue, and Svelte implement different reactivity strategies to optimize performance and maintain consistency.
