Data Types

TuffSeal is dynamically typed.

Primitive Types

let n = 42; // integer / number
let s = "hi!";  // string

Arrays

let arr = [1, 2, 3, "four"];
print(arr[0]);

NOTE: Array indexing starts at 0. arr[0] would return "1" because the object with the index 0 inside the array is the number one.

Dictionaries

let dict = {
    a: "Hello!",
    b: 5
}

print(dict.a);
print(dict["b"]);

type() Builtin

TuffSeal provides a builtin function for detecting what type is a specific variable.

let arr = [1, 2, 3]; // array
print(type(arr)); // "array"

//--------------------------//
let dict = {
    a: 5,
    b: 10
}

print(type(dict)); // "dictionary"

Possible Values

• "fn" (functions)
• "int" (numbers / integers)
• "str" (strings)
• "bool" (booleans)
• "array" (arrays)
• "dictionary" (dictionaries)
• "luau_external" (other)

NOTE: If a variable has a type that doesn't exist inside of TuffSeal, but exists in Luau, it will return luau_external
