This document provides an introduction to CoffeeScript and how to use it. It discusses running CoffeeScript in a web browser or on OSX, Linux, and Windows. It then covers CoffeeScript basics like functions, parameters, operators, conditionals, scope, context, properties, default values, splats, and arrays.

3. inWebBrowser
scripttype=”coffee-script.js”
scripttype=”text/coffeescript”
//coffeescriptcode
/script

4. inOSXorLinux
-installnode.js
-installnpm
$npminstall-gcoffee-script
$coffee

5. inWindows

6. Function

7. 함수를정의한다
-

8. 생략
괄호:()
중괄호:{}
세미콜론:;

9. -‘HelloWorld’
do-‘HelloWorld’
(-‘HelloWorld’)()

10. 함수의마지막표현식이
자동으로리턴된다
(return문을사용할수도있다)

11. 이름있는함수는변수에할당
greeting=-‘HelloWorld’

12. 파라미터
print=(msg)-msg

13. Interpolation:“#{}”
p=(msg)-“hello#{msg}”
p=(msg)-‘hello‘+msg

14. +오퍼레이터는공백에따라다르다
‘frends’+5//frends5
‘frends’+5//TypeError

15. Operator
is//===
isnt//!==
not//!
and//
or//||
true,yes,on//true
false,no,off//false

16. Contidional
iftruethen1
1iftrue
iftruethen1else2
1unlesstrue

17. 존재여부확인
값이있거나
undefined나null이아니면
trueunlessa?
a?b
a?=b

18. Scope

19. 변수의범위
모든함수는범위를만든다
변수가할당된최상위범위에서존재
범위밖에서는접근할수없다

20. Context

21. this
@

22. 현재컨택스트로this고정
=
not-

23. 프로퍼티
setName=(name)-@name=name
setName=(@name)-

24. 기본값
func=(a=true)-...

25. Splats:...
func=(a,b...)-
func=(a,b...,c)-
func-(a...,b)-

26. Splats:...
user=[1,2,3,4,5]
[a...,b]=user
