Useful TypeScript types

/** Remove field with value "never" from a Map */
type RemoveNever<Map> = Pick<Map, {
    [K in keyof Map]: Map[K] extends never ? never : K;
}[keyof Map]>;
/** Make fields partial and also recursively make nested fields partial */
type DeepPartial<T> = {
    [K in keyof T]?: DeepPartial<T[K]>;
};
/** Make specified fields optional while leaving the remaining fields the same */
type PartialOnly<T, K extends keyof T> = Partial<Pick<T, K>> & Omit<T, K>;
/** Make all fields optional while leaving the specified fields the same */
type PartialExcept<T, K extends keyof T> = Partial<Omit<T, K>> & Pick<T, K>;
