# The range type

The range type represents a closed range of integers characterized by three values:

1. an inclusive start bound,
2. an exclusive end bound,
3. the interval between values in the range.

As such, very large ranges can be stored, indexed, and enumerated without needing to pre-allocate all possible values in memory.

Ranges are created with the built-in [range] function:

# Print numbers 0 through 4
[cat: **[range: 0; 5]; \n]

##
Output:
0
1
2
3
4
##


Backwards ranges are possible, too; just use a start bound larger than the end bound:

# Print numbers 4 through 0
[cat: **[range: 4; -1]; \n]

##
Output:
4
3
2
1
0
##


By default, [range] uses an interval of 1, but you can change this by adding a third argument:

# Print every second number between 0 and 9
[cat: **[range: 0; 10; 2]; \n]

##
Output:
0
2
4
6
8
