Tables

Tables are SamaLang’s primary and only data structure (inherited from Lua). They can function as arrays, dictionaries, records, or objects.

Creating Tables

Empty Table

ada data = {}

Array (Sequential Keys)

ada buah = {"apel", "mangga", "jeruk"}

tulis(buah[1]) -- Output: apel
tulis(buah[2]) -- Output: mangga
tulis(buah[3]) -- Output: jeruk

Dictionary (Key-Value Pairs)

ada mahasiswa = {
    nama = "Ahmad",
    umur = 20,
    jurusan = "Teknik Informatika"
}

tulis(mahasiswa.nama) -- Output: Ahmad
tulis(mahasiswa["umur"]) -- Output: 20

Accessing Elements

ada buah = {"apel", "mangga", "jeruk"}

-- Bracket notation
tulis(buah[1])

-- Dot notation (for string keys)
ada profil = {nama = "Sari", kota = "Jakarta"}
tulis(profil.nama)
tulis(profil["kota"])

Modifying Tables

ada buah = {"apel", "mangga"}

-- Add element
buah[3] = "jeruk"

-- Modify element
buah[1] = "pisang"

tulis(buah[1]) -- Output: pisang

Table Length

Use # to get the number of elements in a sequential table:

ada angka = {10, 20, 30}
tulis(#angka) -- Output: 3

Iterating Over Tables

Numeric For Loop

ada buah = {"apel", "mangga", "jeruk"}

untuk i = 1, #buah boat
    tulis(buah[i])
jure_mo

Generic For with `ipairs` (Sequential)

ada warna = {"merah", "biru", "hijau"}

untuk i, v in ipairs(warna) boat
    tulis(i .. ": " .. v)
jure_mo

Generic For with `pairs` (All Keys)

ada mahasiswa = {nama = "Ahmad", umur = 20}

untuk k, v in pairs(mahasiswa) boat
    tulis(k .. " = " .. tostring(v))
jure_mo

Nested Tables

Tables can contain other tables:

ada kelas = {
    {nama = "Ahmad", umur = 20},
    {nama = "Sari", umur = 21},
    {nama = "Budi", umur = 19}
}

tulis(kelas[1].nama) -- Output: Ahmad
tulis(kelas[2].umur) -- Output: 21

Common Table Functions

Function	Description	Example
`table.insert(t, pos, val)`	Insert at position	`table.insert(buah, 2, "mangga")`
`table.remove(t, pos)`	Remove at position	`table.remove(buah, 1)`
`table.sort(t)`	Sort alphabetically	`table.sort(buah)`
`ipairs(t)`	Iterator for arrays	`for i, v in ipairs(t) boat`
`pairs(t)`	Iterator for all keys	`for k, v in pairs(t) boat`
