什么是constructor.prototype引用？(What is constructor.prototype refering to?)

 在typescript中阅读Decorators的文档（我在这个片段上讨论了： 
 
function sealed(constructor: Function) {
    Object.seal(constructor);
    Object.seal(constructor.prototype);
}
 
 
 
 当执行@sealed时，它将密封构造函数及其原型。 
 
 
 constructor.prototype指向什么？ 这种典型的继承有时会让人感到困惑。 

Reading the documentation for Decorators in typescript (I stumpled upon this snippet:
 
function sealed(constructor: Function) {
    Object.seal(constructor);
    Object.seal(constructor.prototype);
}
 
 
 
When @sealed is executed, it will seal both the constructor and its prototype.
 
 
What does constructor.prototype point to? This prototypical inheritance can be a tad confusing at times.
