TypeScript 定義型別物件

官方文件在定義物件型別時，用分號 隔開

var employee : { 
    id: number; 
    name: string; 
}; 

employee = { 
  id: 100, 
  name : "John"
}

之後學到 interface 介面 ，和物件整合

有一些關於要使用分號還是逗號
Should TS interface have a comma or semicolon?

In TypeScript, interfaces and type literals can have members separated by a comma or a semicolon.

It's a good idea to have a consistent style.

They're both valid, but TypeScript prefers semicolon.
