CoffeeScript adalah bahasa kecil yang menyusun/kompil satu-per-satu menjadi setara JavaScript, dan tidak ada interpretasi di runtime.
|
|
Sebagai salah satu pengganti kepada JavaScript, CoffeeScript mencuba yang terbaik untuk output kod JavaScript yang mudah dibaca, cantik-dicetak dan berfungsi lancar, yang mana berfungsi baik pada setiap runtime JavaScript.
|
|
|
|
Lihat juga [Laman sesawang CoffeeScript](http://coffeescript.org/), yang mana ada tutorial lengkap untuk CoffeeScript.

# CoffeeScript adalah bahasa hipster.
|
|
# Ia beredar mengikut trend kebanyakkan bahasa moden.
|
|
# Jadi komen sama seperti Ruby dan Python, ia menggunakan simbol nombor.
|
|
|

|
Blok komen seperti ini, dan ia terjemah terus ke '/ *'s dan '* /'s
|
|
untuk keputusan kod JavaScript.

Sebelum meneruskan anda perlu faham kebanyakkan daripada
|
|
JavaScript adalah semantik.

# Menetapkan:
|
|
number = 42 #=> var number = 42;
|
|
opposite = true #=> var opposite = true;
|
|
|
|
# Bersyarat:
|
|
number = -42 if opposite #=> if(opposite) { number = -42; }
|
|
|
|
# Fungsi:
|
|
square = (x) -> x * x #=> var square = function(x) { return x * x; }
|
|
|
|
fill = (container, liquid = "coffee") ->
|

|
|
# }
|
|
# return "Filling the " + container + " with " + liquid + "...";

|
|
# Julat:
|
|
list = [1..5] #=> var list = [1, 2, 3, 4, 5];
|
|
|
|
# Objek:
|
|
math =
|
|
root: Math.sqrt
|
|
square: square
|
|
cube: (x) -> x * square x
|
|
#=> var math = {

# Splats:
|
|
race = (winner, runners...) ->
|

print winner, runners
|
|
#=>race = function() {

# Kewujudan:

alert "I knew it!" if elvis?

|
|
# Pemahaman array:

|
|
#=>cubes = (function() {

foods = ['broccoli', 'spinach', 'chocolate']
|
|
eat food for food in foods when food isnt 'chocolate'
|
|
#=>foods = ['broccoli', 'spinach', 'chocolate'];
|
|
#
|
|
#for (_k = 0, _len2 = foods.length; _k < _len2; _k++) {
