# NodeJS classes benchmark
A simple (and non scientific) benchmark to compare the speed and memory usage of `prototype`, `classes`, `plain objects` and `plain functions` on object instances (methods) and that are static (static methods / plain functions).
## Results
**Specs:**
- OS: Ubuntu 20.04.2 LTS x86_64
- CPU: Intel i7-10510U (8) @ 4.900GHz
- Memory: 15747MiB
- NodeJS: v14.8.0
> ℹ️ You results may differ
