Functions

Function Declarations

function functionName(parameterList): ReturnType {
    // Function body
}

• parameterList is a comma-separated list of parameters with their types.

• ReturnType is optional; if omitted, the function does not return a value.

Parameters

Parameters are declared with their name and type.

function add(a: uint256, b: uint256): uint256 {
    return a + b;
}

Return Types

Specify the return type after the parameter list and a colon.

function isPositive(number: uint256): bool {
    // Function body
}

Note: The bool type may not be fully implemented yet; currently, functions can return uint256.

Return Statements

Use the return keyword to return a value from a function.

return expression;
