javaScript) 돈 콤마 찍기 꿀팁

const cn1 = n1.toLocaleString('ko-KR');


console.log(cn1)  //12,345.679

2. toLocaleString() 함수 이용하기

toLocaleString() 함수

toLocaleString() 함수를 사용하여 간단하게 천단위마다 콤마를 추가할 수 있습니다.

number.toLocaleString(locales, options)

toLocaleString() 함수는 숫자를 로컬의 language format에 맞는 문자열로 변경해 줍니다.

파라미터로 아무것도 전달되지 않으면 사용자 로컬 환경의 locale을 default로 사용합니다.
