SnakeCase - Convert a string literal to snake-case (foo_bar). SnakeCasedProperties - Convert object properties to snake-case (foo_bar). SnakeCasedPropertiesDeep - Convert object properties to snake-case recursively (foo_bar). ScreamingSnakeCase - Convert a string literal to screaming-snake-cas...
条件类型还可以与映射类型结合使用,以实现更灵活的类型转换。 typeFunctionPropertyNames<T> = { [Kinkeyof T]: T[K]extendsFunction? K :never; }[keyof T];typeFunctionProperties<T> =Pick<T,FunctionPropertyNames<T>>;classPerson{name:string;age:number;greet() {console.log(`Hello, my name is${t...
