+title: Define Ranges Array
+chapter: Arrays

+## Problem
+
+You want to define a range in an array.
+
+## Solution
+
+There are two ways to define a range of array elements in CoffeeScript.
+
+{% highlight coffeescript %}
+
+myArray = [1..10]
+# => [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]
+
+{% endhighlight %}
+
+{% highlight coffeescript %}
+
+myArray = [1...10]
+# => [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
+
+{% endhighlight %}
+
+We can also reverse the range of element by writing it this way.
+
+{% highlight coffeescript %}
+
+myLargeArray = [10..1]
+# => [ 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 ]
+
+{% endhighlight %}
+
+{% highlight coffeescript %}
+myLargeArray = [10...1]
+# => [ 10, 9, 8, 7, 6, 5, 4, 3, 2 ]
+
+{% endhighlight %}
+
+## Discussion
+
+Inclusive range always define by '..' operator.
+
+Exclusive range define by '...', and always omit the last value.
