golang中的可选类型，如打字稿

问题描述：

In typescript, you can have an optional type like :

interface SquareConfig {
    color?: string;
    width?: number;
}

Is this allowed in Golang? How do I achieve that?

在打字稿中，您可以有一个可选类型，例如： p>

 接口SquareConfig {
颜色？：字符串； 
宽度？：数字； 
} 
  code>  pre> 
 
 在Golang中允许吗？ 我该如何实现？   p> 
  div>

答

Is this allowed in Golang?

No.

Btw: The language is called "Go".

How do I achieve that?

You do some programming, like using pointers or adding a bool which indicates validity of the fields.
