Strings

The syntax for string variables is relatively unchanged, and looks as follows:

let helloWorld = "Hello, world!";

This variable can be used anywhere within its scope, like in this block:

let helloWorld = "Hello, world!";
println(helloWorld);

As might be expected, this would print Hello, world!.

Strings can be concatenated with the + operator. It cannot add two differing types outside of the println built-in, such as an integer and a string.

For example, this program outputs Hello, world!.

let hello = "Hello, ";
let world = "world!";
let helloWorld = hello + world;

println(helloWorld);

This program errors because string and num are of mismatching types (string and integer):

let str = "Look, a string!";
let num = 3;

println(str + num);

Integers can be observed more in-depth on their page.

You can also split a string into an array of strings, like so:

let str = "Item 1, Item 2, Item 3";
let array = str.split(", ");
println(array);

["Item 1", "Item 2", "Item 3"]
