With jQuery, you'll be seeing the dollar sign a lot.
jQuery에서는 $ 기호를 많이 보게 될 거예요
But what is the dollar sign?
$는 무엇일까요?
Is it some special JavaScript keyword?
특별한 자바스크립트 키워드라도 되나요?
I'll press Enter, and, low and
엔터를 누르고 아래를 보면
behold, we see the exact same object that we saw before.
우리가 전에 보았던 것과 똑같은 객체를 볼 수 있습니다
As it turns out, the jQuery object and
결국 jQuery 객체와
the dollar sign are mapped to the exact same thing.
$는 정확히 같은 것을 지칭한다는 것이죠
So, what is this dollar sign?
흠, 그래서 $가 뭐냐고요?
The dollar sign is a character like any other.
$는 다른 것들과 같이 문자입니다
We could even reassign it as variable to something else if we wanted to.
우리는 원한다면 그 $를 어떤 것의 변수로 지정할 수도 있어요
For instance var $ equals cameron.
예를 들어 ‘var $ = cameron’을 입력 한 후
And then when I type in the dollar sign and press Enter, we see cameron.
$를 입력하고 엔터를 누르면 cameron이 나오죠
With jQuery the dollar sign is just a pointer to the same JavaScript object we
jQuery에서 $는 그저 이전에 보았던 것과 같은 자바스크립트 객체를 가리키는
saw before.
포인터일 뿐이죠
In the spirit of making your front-end code easier to write,
프론트-엔드 코드를 쓸 때
jQuery uses the dollar sign because because it's faster and
jQuery라는 단어보다 더 빠르게 타이핑하기 쉽다는 점에서
easier to type than the whole word jQuery.
$를 씁니다
In fact, some other JavaScript libraries use the dollar sign as well.
사실 몇몇의 다른 자바스크립트 라이브러리들도 $를 써요
For instance, the MooTools library also maps the dollar sign to a variable
예를 들어 MooTools 라이브러리도 $를 변수로 지정하죠
