Variables

Variables in Zink are declared with let. They are dynamically typed — no type annotations needed.

Declaration

let x = 42
let name = "Alice"
let active = true
let nothing = null

Reassignment

Variables can be reassigned to any type:

let x = 10
say x        # 10

x = "hello"
say x        # hello

Types

Zink has five value types:

Type	Example	Notes
Number	42, 3.14	64-bit floating point
String	"hello"	Double-quoted, with interp.
Boolean	true, false	Logical values
Null	null	Absence of a value
Array	[1, 2, 3]	Ordered, dynamic-length

Naming Rules

• Must start with a letter or underscore
• Can contain letters, digits, and underscores
• Case-sensitive (name ≠ Name)

let my_var = 1       # ok
let _private = 2     # ok
let camelCase = 3    # ok

Scope

Variables declared inside a block ({ }) are local to that block:

let x = "outer"
if true {
  let x = "inner"
  say x              # inner
}
say x                # outer
