# TypeScript Exercises

원티드 세션에서 추천 받은 타입스크립트 문제 풀이 사이트 [링크](https://typescript-exercises.github.io/#exercise=1\&file=%2Fnode_modules%2Ftype-assertions%2Findex.ts)

총 16단계의 문제가 있고, 9단계 이상이면 타입 스크립트에 자신감을 가져도 된다고 한다.

현재 타입스크립트 수준 확인 겸 풀이를 시작해보자 !

    The goal: Let everyone play with many different TypeScript features
    and get an overview of TypeScript capabilities and principles.

    Things to cover:

        1. Basic typing.
        2. Refining types.
        3. Union types.
        4. Merged types.
        5. Generics.
        6. Type declarations.
        7. Module augmentation.
        8. Advanced type mapping.

    Rules and principles:

        1. Avoid using "any" type at all costs.
        2. Difficulty quickly grows one exercise after another.
        3. Feel free to send pull requests if you've come up
           with improvements!
        4. Provide feedback to the creator of these exercises.
        5. Enjoy.
