Purpose
The Reflect object is used as namespace
for functions related to JavaScript the language.
Reflect's methods typically:
- Provides a function form of operators. For example,
Reflect.get( obj, key )is the same asobj[key] - Provide a more strict/improved version of existing methods. For example,
Reflect.getPrototypeOf( obj)is same asObject.getPrototypeOf( obj), but will throw error if obj is not a object type.
