JavaScript Strings: Methods and Examples Explained

A string in JavaScript is a sequence of characters used to represent textual data. Strings are immutable, meaning their content cannot be changed once created.

Creating Strings

You can create a string in three ways:

Using Single Quotes ('):

Example

let str = 'Hello, World!';

Using Double Quotes ("):

Example

let str = "Hello, World!";

Using Template Literals (Backticks ` `):

Supports multi-line strings
Allows string interpolation (${expression})

Example

let name = 'John';

let greeting = `Hello, ${name}!`;

console.log(greeting); // Output: Hello, John!
