Strings

A string is text — a name, a message, a label. You write it inside quotes: 'Spark' or 'Game Over'. Single or double quotes both work; just start and end with the same one.

1. Make and show text

let name = 'Spark';

function draw() {
  cls(1);
  print('Hello!', 8, 8, 10);
  print(name, 8, 20, 7);
}

2. Join strings with +

Between two strings, + glues them together — this is called concatenation. Build a bigger message from pieces:

let name = 'Spark';

function draw() {
  cls(1);
  print('Hi ' + name + '!', 8, 8, 10);
}

3. Numbers become text automatically

When you + a string and a number, JavaScript turns the number into text so it can join. That is exactly why a score shows up when you glue it onto a label:

let score = 42;

function draw() {
  cls(1);
  print('Score: ' + score, 8, 8, 7);   // the number joins as text
}

You can also turn a number into text on purpose with String(n), but with print the automatic join usually does the job.

What you learned

• A string is text in quotes: 'Spark'.
• + between strings joins them (concatenation); spaces go inside the quotes.
• A number joined to a string becomes text automatically — how print shows scores.
• '3' + 4 is '34', not 7 — + joins whenever text is involved.
