Intro Filtering was completely removed from the project. It turned out that this feature was just not needed for the end-user and we spent a lot of time just because our office manager told us to do so. Next time we should instead listen to the product management. Anyway we have a new plan. CEO's friend Nick told us that if we randomly swap user names from time to time in the community, it would..

Intro Filtering requirements have grown. We need to be able to filter any kind of Persons. 필터링 요구사항이 늘었습니다. 이제 Person의 모든 종류를 구분해야합니다. Exercise Fix typing for the filterPersons so that it can filter users and return User[] when personType='user' and return Admin[] when personType='admin'. Also filterPersons should accept partial User/Admin type according to the personType. `criteria` argument sh..

Intro Time to filter the data! In order to be flexible we filter users using a number of criteria and return only those matching all of the criteria. We don't need Admins yet, we only filter Users. 데이터를 선별할 차례입니다! 보다 유연해지기 위해 우리는 기준을 표시하는 숫자를 이용하여 유저들을 필터링하고, 오직 이 모든 기준에 맞는 유저들만 리턴해야합니다. 아직 Admin들은 필요하지 않고 User들만 필터링하면 됩니다. Exercise Without duplicating type structures, modify filterUsers functio..

Intro As we introduced "type" to both User and Admin it's now easier to distinguish between them. Once object type checking logic was extracted into separate functions isUser and isAdmin - logPerson function got new type errors. 유저와 어드민에 대해 type을 소개했듯이, 이제 이 둘을 구분하는건 쉬워졌습니다. 로직을 검사하는 객체 타입을 추출해서 isUser과 isAdmin 함수에 분리해서 넣었더니 logPerson 함수에 새로운 타입에러가 생겼습니다 Exercise Figure out how to help TypeScrip..

Intro Since we already have some of the additional information about our users, it's a good idea to output it in a nice way. 이미 유저의 추가적인 정보를 알고 있기 때문에, 멋진 방법으로 이를 표출하면 좋을 것 같다 Exercise Fix type errors in logPerson function. logPerson function should accept both User and Admin and should output relevant information according to the input: occupation for User and role for Admin. logPerson 함수의 타입에러..

Introduce All 2 users liked the idea of the community. We should go forward and introduce some order. We are in Germany after all. Let's add a couple of admins. Initially, we only had users in the in-memory database. After introducing Admins, we need to fix the types so that everything works well together. 두명의 유저 전부 커뮤니티의 아이디어가 마음에 들었고, 우리는 이제 소개를 해야합니다. admin 몇명을 추가해봅시다. 처음에 우리는 데이터베이스에만 유저를 저장..

Introduce We are starting a small community of users. For performance reasons we have decided to store all users right in the code. This way we can provide our developers with more user-interaction opportunities. With user-related data, at least. All the GDPR-related issues will be solved some other day. This would be the basis for our future experiments during these exercises. 우리는 이제 유저들을 위한 작은..
