In this example, we create a proxy that caches the results of an expensive computation. The first time the expensiveComputation method is called, the proxy computes the result and caches it. Subsequent calls return the cached result immediately.
The text dissolved. A video file opened on the screen. It was low resolution, grainy, clearly processed by the archaic software. It showed a woman sitting on a porch, wrapped in a blanket, looking at a stormy sky. She turned to the camera and smiled. It was a flawed smile—tired, slightly blurry, the audio slightly out of sync.

In this ES2021 example, we create a proxy that prevents the setting of negative values for a specific property.
By 2021, developers realized that using Reflect inside a proxy gave exactly critical advantages: In this example, we create a proxy that
The brilliance of the 2021 iteration of this project lies in its exploration of "reflectivity." Reflection is not merely a visual phenomenon here; it is a feedback loop. When a viewer interacts with the work, their movements are captured, distorted, and projected back as a proxy. This creates a sense of "digital uncanny," where the representation feels familiar yet fundamentally alien. It forces the audience to confront how much of their identity is currently being managed by third-party proxies—from social media algorithms that curate our personalities to the metadata that tracks our every move.
