Proxying a target ECMAScript object regardless whether the target ECMAScript object is a read-only object

Abstract:

Techniques are described herein that are capable of proxying a target ECMAScript object regardless whether the target ECMAScript object is a read-only object. For instance, when a determination is made that a requested target ECMAScript object includes at least one read-only property, the requested target ECMAScript object is proxied by performing operations, which include creating a new target ECMAScript object to replace the requested target ECMAScript object and associating handler objects, which are configured to perform respective operations on a property of the requested target ECMAScript object, with the new target ECMAScript object to generate a proxied target ECMAScript object.
