proxy-pattern

You intercept object property reads and writes in JavaScript for validation by defining a handler with get and set traps. This Proxy pattern observes and modifies interactions to ensure data integrity before properties are accessed or changed.

The JavaScript Proxy pattern is used for intercepting and standardizing interactions with data objects. It enables validation, auditing, logging, and controlled access when properties are read, written, or functions are invoked.

Use Reflect inside proxy traps to perform safe reads and writes by forwarding the default object behavior. Applying Reflect methods within get and set traps maintains standard data integrity while allowing custom interception logic.

Yes, you can apply the Proxy pattern to log function invocations on UI models. Defining a handler with traps allows you to observe and audit function calls and property interactions across model objects.

No, the JavaScript Proxy pattern requires no external dependencies for access control. It uses built-in language features like handler traps and Reflect to intercept and manage object interactions natively.
