To declare const variables and const functions in the Cangjie language, you use specific syntax rules that enforce compile-time evaluation and immutability. This Skill demonstrates the exact declaration syntax and provides minimal examples like a const Point initializer.

Compile-time evaluation for const init usage in Cangjie calculates variable and function values during the compilation process rather than at runtime. This mechanism ensures true immutability and optimizes performance by resolving constants before execution.

You should apply const constructs in real Cangjie projects when you need guaranteed immutability and compile-time evaluation. Using const is ideal for fixed configuration values and pure functions that do not rely on runtime state.

Const variables in Cangjie differ from regular immutable variables because their values must be fully evaluable at compile time. Regular immutable variables are fixed at runtime, whereas const variables are resolved entirely during compilation.

Cangjie const functions support compile-time evaluation, but they must adhere to specific language syntax rules. They are suitable for pure calculations like initializing a const Point with x and y fields, though complex runtime-dependent logic remains restricted.
