Strings

Strings

Strings hold text. You can write them with double quotes, single quotes, or backticks:

let a = "hello";
let b = 'world';
let c = `hello world`;  // template literal

Concatenation

Use + to join strings together:

let first = "Hello";
let second = "World";
console.log(first + ", " + second + "!");  // Hello, World!

Template Literals

Backtick strings let you embed expressions with ${...}:

let name = "Alice";
let age = 30;
console.log(`${name} is ${age} years old`);  // Alice is 30 years old

Useful Methods

let s = "Hello, World!";
console.log(s.length);           // 13
console.log(s.toUpperCase());    // HELLO, WORLD!
console.log(s.toLowerCase());    // hello, world!
console.log(s.includes("World")); // true
console.log(s.slice(7, 12));      // World
