Which framework—React, Vue, or Angular—offers the best memory usage and rendering performance in modern SPAs?

Explores real-world differences in memory consumption and UI update speed across three leading frameworks, based on performance studies.

• Vue consistently offers the best memory efficiency and fastest rendering thanks to its reactive tracking system. • React remains close behind, using Virtual DOM and concurrent rendering for strong runtime performance. • Angular is typically heavier in memory and slower in updates—unless optimized with AOT compilation, the Ivy renderer, and OnPush detection mechanisms Tags: frontend, performance, memory-usage, reactjs, vuejs, angular
