Standard types

These types come with every program out of the box: numbers and text, arrays and lists, references, and nullability. Read these before moving on to Custom types.

• Builtin types are numbers, booleans, and characters.
• Arrays are fixed-size sequences, including slices.
• List is a resizable array.
• Strings are text.
• Vector math does element-wise arithmetic on fixed-size arrays.
• References and pointers borrow values and address memory.
• Nullable types may or may not hold a value.
