# Project 1: Implementation of Active Expressions using JavaScript Proxies

![](screenshot.png)

Goals:
- Implement a change detection strategy based on JavaScript Proxies in Lively 4
- Identify trade-offs: Compare with other implementation strategies
  - Conceptual limitations
  - Runtime overhead (performance benchmarks)
- Integrate into existing benchmark suite
