array

A sequence of values.

You can construct an array by enclosing a comma-separated sequence of values in parentheses. The values do not have to be of the same type.

You can access and update array items with the .at() method. Indices are zero-based and negative indices wrap around to the end of the array. You can iterate over an array using a for loop. Arrays can be added together with the + operator, joined together and multiplied with integers.

Note: An array of length one needs a trailing comma, as in (1,). This is to disambiguate from a simple parenthesized expressions like (1 + 2) * 3. An empty array is written as ().

Example

#let values = (1, 7, 4, -3, 2)

#values.at(0) \
#(values.at(0) = 3)
#values.at(-1) \
#values.find(calc.even) \
#values.filter(calc.odd) \
#values.map(calc.abs) \
#values.rev() \
#(1, (2, 3)).flatten() \
#(("A", "B", "C")
    .join(", ", last: " and "))

Converts a value to an array.

Note that this function is only intended for conversion of a collection-like value to an array, not for creation of an array from individual items. Use the array syntax (1, 2, 3) (or (1,) for a single-element array) instead.

#let hi = "Hello 😃"
#array(bytes(hi))
