JavaScript Proxy Summary

The JavaScript Proxy object is a built-in feature that allows you to create a proxy for another object, which can intercept and redefine fundamental operations for that object. This enables adding extra functionality or controlling access without modifying the original object directly.

Pros:

• Separation of concerns: The proxy can handle specific tasks independently from the subject.
• Easy to implement and extend functionality without altering the original subject.
• Can provide a level of security by controlling access to the subject.

Cons:

• May introduce complexity due to the additional layer of abstraction.
• Can cause a decrease in performance, as the proxy may require additional processing.

Example Explanation:

In this example, the player can collect coins in a simple game. The Player object represents the player, and the Proxy object controls access to the Player object, keeping track of the player's score and applying a multiplier to increase the score based on certain conditions. We use the built-in JavaScript Proxy object to add extra functionality without altering the original Player object.
