object.js

+// 증감 연산을 왼쪽에 붙이냐, 오른쪽에 붙이냐에 따라 값이 달라짐.
+// 이 부분 모르겠으니까 집가서 다시봐라..
+let a = 2;
+// let b = a++; // -> 이렇게 하면 b가 2가 나옴
+let b = ++a; // -> 이렇게 하면 b가 3이 나옴
+
+console.log(b);


let b = a++; 가 2인 이유는
대입 연산을 먼저 진행한 후에 후치연산인 ++를 진행해서 그렇답니다!
그러니께 78번을 지나면 b는 2가 되고 a는 3이 되겠죠,,
반대로 79번은 대입 연산을 하기 전에 ++를 해줘서 a를 먼저 증가 시킨 후에 대입을 하는거죠,,
그니간 79번을 지나면 a와 b 모두 3이 되는거랍니다!! ㅋㅋ
ㅋㅋㅋㅋ

variable.js

+// 여기서부터는 scope 연습
+
+// if (true) {
+//     var x = 'var variable';
+
+// }
+
+// console.log(x);
+
+// if (true) {
+//     const y = 'const variable';
+// }
+
+// console.log(y); // 여기서 에러가 난다. 이유는 const는 블록 스코프니까.
+
+
+// var 변수는 function 스코프인데 가능할까?
+
+
+function foo() {
+    if (true) {
+        var name = '채정아';
+        console.log('if-block', name);
+    }
+    console.log('function-block-', name); // 여기서 var이 호출된 거는 상관없음
+}
+
+console.log('global-', name); // 여기서 에러가 남 -> 함수 내부에서 선언이 되어 있기 때문에 
+
+


스코프가 헷갈리신다면,,,,,,
제가 자료를 보내드리죠...

진짜 스승님이신가요?

object.js

+console.log(sopt.group);
+sopt.introduce();
+console.log(sopt.season);

왜 빈줄이 두개죠?

제성합니당..^^

object.js

곱창은 좀.

반영하겠습니다^^

variable.js

+// console.log(name3) // 임원진안짱 출력
+

+// name4 = "김혜수";


하잉 ㅋㅋ

+        console.log('if-block', name);
+    }
+    console.log('function-block-', name); // 여기서 var이 호출된 거는 상관없음


print("function-block-\(name)")

@hyesuuou 굉장히 킹받지만, 역시 간결해서 좋은 것 같습니다. ^^

수고하셨습니다~!

typeprac.ts

+// 1. as : 짱정아가 사용하는 방법! 나도 이거 써야징
+
+let yourName: any = '채리지아';
+let yourNameLength: number = (yourName as string).length; // 스위프트의 타입캐스팅임


저도 짱정아님 방식 채택~!

@oownahcohc 마음에 드시나요?

age가 좀 있는 편이네요??

+}
+
+if (A === y) {
+    console.log('A===문자열5, 값과 타입도 같음');

=== 은 swift에는 없나요?

넵 있습니다! 그런데 소연님 왜 물어보시져? 아시잖아여.

random.ts

+interface Members {
+  name: String;

+}
+
+// 기억하기! : interface에는 함수가 들어갈 수 있음
+interface Dinner {
+  member: Members[];
+  shuffle(member: Members[]): Members[];
+  organize(member: Members[]): void;
+}


인터페이스 모듈화 부탁드려요 불 - 편 합니다 ㅋㅋㅋㅋㅋ

orijoon98 · 2022-04-08T13:13:08Z

random.ts

+    const ob = array.filter((array) => array.group === "ob");
+    const yb = array.filter((array) => array.group === "yb");
+
+    let dinnerMember: String[] = [ob[0].name, yb[0].name];


filter를 사용하셔서 인덱스로 접근을 해야 하는게 살짝 아쉽네요.
find에 대해서 알아보시는 건 어떨까요? ㅎㅎㅎㅎ

리팩토링 수고요

+    let dinnerMember: String[] = [ob.name as String, yb.name];


ob는 타입단언 해줬는데 왜 yb는 안해줬죠? 와이비 차별하시나요?

사실 안하는게 맞을걸??

ㅋㅋㅋㅋㅋㅋㅋ아 제발ㅋ 지웟어 어서 approved 눌러종

orijoon98 · 2022-04-08T13:55:38Z

-    let dinnerMember: String[] = [ob[0].name, yb[0].name];
+    let dinnerMember: String[] = [ob.name as String, yb.name];


yb 는 왜 안해줘요??? 다시~~~!!!!

진짜 개킹받네여;;ㅋ ㅈㅅㅈㅅ
