In Wave, variables are declared using the var keyword, followed by the variable name and its type. Wave supports a variety of data types, including integers, floating-point numbers, and strings.

Example:

var num: i32 = 42;
var name: str = "Wave";

Constants are defined using the const keyword, ensuring that their values cannot be changed once set. Literals are basic values such as numbers or strings used directly in code.

Example:

const MAX_LIMIT: i64 = 1000;
const GREETING: str = "Hello, Wave!";

Wave supports single-line and multi-line comments. Single-line comments start with //, while multi-line comments are enclosed within /* */.

Example:

// This is a single-line comment.
/*
This is a
multi-line comment.
*/
