Type System

DTL has a strong type system that helps catch errors early. Types can be explicitly declared or automatically inferred from values.

Type Inference

DTL automatically infers types from values, so you rarely need to specify them explicitly:

Explicit Types

You can also explicitly declare types using a colon (:):

Available Types

Color

Represents color values in various formats:

Size

Represents dimensional values with units:

Number

Represents numeric values without units:

Font & FontFamily

Represents font names and font stacks:

FontWeight

Represents font weight values:

Duration

Represents time durations:

String

Represents text values:

Array Types

Arrays can hold multiple values of the same type:

Type Checking

DTL performs type checking to ensure type safety. Type mismatches will result in compilation errors:

Type Coercion

Some types can be automatically coerced in certain contexts. For example, numbers can be used where sizes are expected:
