Hello, Leata! After about 4 months, you must have gotten used to the work to some extent 👍 While developing, if you come across an unfamiliar part that makes you think, "What was that?", you may waste a lot of time on something that is not really a big deal. In such cases, if you have a solid foundation, you will be able to quickly recall it while saying, "Oh, that's right! " 😉 If you watch all of this lecture and solve the quiz yourself, you will gain confidence. And when you gain confidence, you will be able to develop more boldly. I hope this lecture will help Leata build up her coding basics 💪. In the near future, you will smile and say, "I've been through that too.. 🤔 ㅎㅎ"! Thank you. - I also code
