.vscode 에 다양한 설정을 할 수 있습니다! 개발자 경험(DX)을 향상시킬 때 큰 도움이 됩니다.
특히 협업 및 팀프로젝트를 진행할 때 모두 동일한 환경에서 개발을 할 수 있도록 도와줍니다.
다양한 시도는 언제나 좋습니다~👍

객체 타입을 선언할 때 let과 const의 차이점은 무엇일까요?
만약 const를 사용한다면 어떤 이점이 있을까요?

purchaseQuantityInput.value 값이 없을 수 있기 때문에(undefined) OR 연산자와 함께 값을 잘 초기화 하셨네�요👍

Suggested change
| purchaseQuantityInput.addEventListener('input', function () { | |
| const count = parseInt(purchaseQuantityInput.value) || 0; | |
| purchaseQuantityInput.addEventListener('input', function (event) { | |
| const count = parseInt(event.target.value); |
이런식으로 event 객체를 사용해서 값을 표현할 수 있습니다. 실제로 자주 사용하는 방식이기도 하고, 이벤트가 발생했을 때 값을 가져오기 때문에 더 의도에 맞게 표현할 수 있습니다.
| const resultTextDiv = document.createElement("div"); | ||
| resultTextDiv.className = "result-text-div"; | ||

| const matchCount = userNumbers.filter(num => correctNumbers.includes(num)).length; |

filter 고차함수 좋습니다. 고차함수는 선언적으로 프로그래밍 할 수 있고, 코드의 의도가 명확해서 정말 자주씁니다.
