Which front end JavaScript framework is most efficient in memory and rendering performance—React, Vue, or Angular?

Compares frameworks based on memory footprint and UI rendering benchmarks in real-world apps (2025).

Benchmark data shows: • Vue uses the least memory and renders fastest due to its reactive system. • React performs nearly as well with virtual DOM diffing and concurrent rendering optimizations. • Angular has higher memory usage unless enhanced with AOT, Ivy, and OnPush strategies.
