What's a String?

A string is just text data, a sequence of characters.

A string can be:

• empty

let emptyString = "";

• a single character

let lowercaseA = "a";
let smileyFace = "😊";
let firstLetterOfHewbrewAlphabet = "א";
let space = " ";
let number = "1";

• a word

let butterfly = "Schmetterling";

• a sentence

let typingPractice = "The quick brown fox jumped over the lazy dog.";

A string can even contain a whole book.

To create a string, you need to enclose the text in quotation marks. You can use single or double quotes, but they have to match.

let singleQuotes = 'Hello, World!';
let doubleQuotes = "Hello, World!";

// but never...
let mismatchedQuotes = 'Hello, World!";
