String
A string is a sequence of characters encoded in UTF-16. In MoonBit, strings are immutable, which means you cannot change the elements inside a string.
MoonBit supports C-style escape characters in strings and chars, such as \n (newline),
\t (tab), \\ (backslash), \" (double-quote), and \' (single-quote).
Unicode escape characters are also supported. You can use \u{...} (where ... represents
the Unicode character's hex code) to represent a Unicode character by its code point.
MoonBit also supports string interpolation written like \{variable}, which allows you to embed expressions into strings.
fn main {
let str = "Hello, World!"
// Access a character by index.
let c : Char = str[4]
println(c)
let c2 = 'o'
println(c == c2)
// Use escape sequence.
println("\nHello, \tWorld!")
println("unicode \u{1F407} is a rabbit")
// Concatenate two strings.
println(str + " Hello, MoonBit!")
// Use string interpolation.
let moon = "Moon"
let bit = "Bit"
println("Use \{moon + bit}. Happy coding")
}
