Strings

Strings in Zink are double-quoted and support interpolation.

Basics

let greeting = "Hello, World!"
say greeting   # Hello, World!
say len(greeting)  # 13

String Interpolation

Embed expressions inside { and } within strings:

let name = "Alice"
let age = 30

say "Name: {name}"
say "Age: {age}"
say "Next year: {age + 1}"
say "2 + 2 = {2 + 2}"

Escape Sequences

Escape	Output
\n	Newline
\t	Tab
\\	Backslash
\"	Quote

say "Line one\nLine two"
say "She said \"hello\""
