Data Structures

Arrays are zero-indexed collections. Jackal supports standard iteration and range-based 'in' loops to traverse elements.

let data = ["jack", "john", "davin", "ale"]

for (let i = 0; i < 4; i++) {
    print(data[i])
}

for (i in data) {
    print(data[i])
}

Maps store data in key-value pairs. Values are accessed by providing the corresponding string key within brackets.

let data = {
    "id": 1,
    "name": "ale"
}

println(data["name"])
