这个utility types对于表示将在运行时失败的赋值表达式很有用(即当试图重新分配一个冻结对象的属性时)。比如,Object.freeze: function freeze<Type>(obj: Type): Readonly<Type>; 7、Mutable<Type> 创建一个Mutable类型帮助程序,允许你将所有只读类型转换为可变类型。 8、Exclude<UnionType, ExcludedMembers> 通过从...

Exclude<UnionType, ExcludedMembers> 通过从 UnionType 中排除所有可分配给 ExcludedMembers 的联合成员来构造类型。在实际的 TypeScript 代码中, Exclude类型工具通常用于过滤掉不需要的类型, 例如从函数参数类型中排除某些类型, 或从对象属性类型中排除某些类型。 版本:TypeScript 2.8+ type MyUnion = 'foo' | '...
