Types and Values

Values

Type	Description	Examples
Number	Represents numeric values.	`1`, `3.14`, `-42`
String	Represents sequences of characters, including Unicode code points and escape sequences in the form of `\{0x000}`.	`"hello"`, `"123"`, `"😊"`, `"\u{1F600}"`
Boolean	Represents truth values.	`true`, `false`
Array	Represents ordered collections of values.	`[1, 2, 3]`, `array(1, 2, 3)`
Dict	Represents key-value mappings (dictionaries).	`{"a": 1, "b": 2}`, `dict(["a", 1], ["b", 2])`
Function	Represents executable code.	`def foo(): 42; let name = def foo(): 42;`

Arrays can be accessed using square bracket notation with zero-based indexing:

let arr = [1, 2, 3, 4, 5]

arr[0]     # Returns 1 (first element)
arr[2]     # Returns 3 (third element)
arr[6]     # Returns None

You can also use the get function explicitly:

get(arr, 0)    # Same as arr[0]
arr | get(2)    # Same as arr[2]

Dictionaries can be accessed using square bracket notation with keys:

let d = {"name": "Alice", "age": 30, "city": "Tokyo"}

d["name"]   # Returns "Alice"
d["age"]    # Returns 30
d["city"]   # Returns "Tokyo"

You can also use the get function explicitly:

get(d, "name")   # Same as di["name"]
d | get("age")    # Same as d["age"]

Both arrays and dictionaries support dynamic access using variables:

let arr = [10, 20, 30]
| let index = 1
| arr[index]     # Returns 20

let d = {"x": 100, "y": 200}
| let key = "x"
| d[key]      # Returns 100
