// 1 -> 2 체크 -> (괜찮으면) -> 3 -> 4 -> 1 순으로 실행

 

리스트와 함께 쓰여 각 요소에 대해 코드를 실행할 수도 있다.

let people = ['김', '이', '박', '최', '양','정', '윤'];

// i가 1씩 증가하면서, people 리스트의 원소를 차례대로 불러온다.
for(let i = 0; i < people.length; i++){
	console.log(people[i];
}

딕셔너리를 요소로 갖는 리스트와도 사용이 가능하다.

let scores = [
	{'name' : '김', 'score' : 90}, 
	{'name' : '이', 'score' : 85},
	{'name' : '박', 'score' : 70}, 
	{'name' : '최', 'score' : 50}, 
	{'name' : '양', 'score' : 100}, 
	{'name' : '정', 'score' : 68}, 
	{'name' : '윤', 'score' : 30},
];

// 각 사람의 score 출력
for(let i = 0; i < scores.length; i++){
	console.log(scores[i]);
}

// 70점 미만인 사람의 이름 출력
for(let i = 0; i < scores.length; i++){
	let score = scores[i];
	if(score['score'] < 70){
		console.log(score['name']);
	}
}
