Reflect is the value of the property key "Reflect" of the Global Object
.
console.log(globalThis["Reflect"] === Reflect);

console.log(typeof Reflect === "object");

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.
