내일배움캠프 1일차 / Javascript 연습하기
Javascript를 연습 해보게 되었습니다.
제가 연습한 Javascript코드를 해석 해보겠습니다.
for (let i = 0; i < mise_list.length; i++) {
if (mise_list[i]['IDEX_MVL'] < 40) {
console.log(mise_list[i]['MSRSTE_NM'])
}반복문으로 시작
변수 = i
i = 0
i보다 mise_list.length가 크면 i가 하나씩 늘어남
만약 mise_list[i]번째의 ['IDEX_MVL'] 미세먼지 수치가 40보다 작으면
console.log에 mise_list[i]번째의 ['MSRSTE_NM']지역이름을 표시
코드 작성 후 console.log에서 확인하면 나오는 답
