省略号在 Flow 类型声明中起什么作用？

Question

以下Flow代码中的省略号是什么，它们有什么作用？

export type ListTypeNode = {
  +kind: 'ListType',
  +loc?: Location,
  +type: TypeNode,
  ...
};

Answer 1

这是 Flow 中的新语法，将来会指示此对象类型是不精确的（当常规注释默认为精确对象注释时）。

In a few releases, Flow will begin to treat {foo: number} as an exact object. To indicate inexactness, you must add an ellipsis to the end of an object type: {foo: number, ...}. This new syntax forces the developers to opt into inexactness.
