Proxy - JavaScript | MDN
The Proxy object enables you to create a proxy for another object, which can intercept and redefine fundamental operations for that object. The Proxy object allows you to create an object that can be used in place of the original object, but which may redefine fundamental Object operations like getting, setting, and defining properties. Proxy objects are commonly used to log property accesses, val
Proxy Tutorial
Methods of the handler object that are invoked by manipulating the corresponding proxy are called traps. The full proxy handler API additionally traps calls to new ES5 built-in methods such as Object.keys and Object.getOwnPropertyDescriptor. Fortunately it is not always necessary to implement the full API to build useful proxies, as demonstrated in the following section. A simple profiler Let's co

See also: the discussion thread on the es-discuss mailing list. A tech talk on harmony proxies is available here. To enable ES programmers to represent virtualized objects (proxies). In particular, to enable writing generic abstractions that can intercept property access on ES objects. Driving forces:
