定义区间数组 Define Ranges Array

## 问题 Problem 你想在一个数组中定义一个区间。 You want to define a range in an array. ## 方案 Solution 在CoffeeScript中，有两种方法定义一系列的数组元素。 There are two ways to define a range of array elements in CoffeeScript. ~~~ myArray = [1..10] # => [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ] ~~~ ~~~ myArray = [1...10] # => [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ] ~~~ 我可以使用下面的写法转置一系列的元素。 We can also reverse the range of element by writing it this way. ~~~ myLargeArray = [10..1] # => [ 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 ] ~~~ ~~~ myLargeArray = [10...1] # => [ 10, 9, 8, 7, 6, 5, 4, 3, 2 ] ~~~ ## 讨论 Discussion 闭区间通常使用`..`操作符来定义。 Inclusive range always define by ‘..’ operator. 开区间使用`...`操作符来定义，通常会省略掉最后一个值。 Exclusive range define by ’…’, and always omit the last value.
