Kaba supports 2 types of arrays:
- fixed sized arrays
- dynamically sized arrays, or "lists"
The more common type.
A list of integers has type i32[].
var list: i32[]
list = [1,2,3]
list.add(4)
# -> [1,2,3,4]
len(list)
# -> 4
Element access:
var list = [1,2,3]
print(list[0]) # -> 1 ... since [0] is the first element...
list[1] = 99
# -> [1,99,3]
Slices/sub lists can be accessed via:
var list = [1,2,3,4,5,6,7,8,9]
list[2:5] # (first index):(first after) -> [3,4,5]
Slices can be used to alter elements:
list[2:5] = [-1,-2,-3]
# -> list = [1,2,-1,-2,-3,6,7,8,9]
🔥 Mutability of a list extends to its elements!
Iterating over elements in a list:
for i in [1,2,3]
print(i)
Here, i is immutable! To change the elements, we need for mut:
var list = [1,2,3]
for mut i in list
i *= 10
# -> [10,20,30]
We can also iterate including the indices and values:
for i=>value in [100,200,300]
# ...
# i=0, value=100
# i=1, value=200
# i=2, value=300
Data pilelines can be used to transform, filter and sort arrays:
[1.0, 2.0, 3.0] |> sin |> sort |> filter(x => x>0) |> sum
An array with 100 integer elements is i32[100].
