    In JavaScript, a string is a sequence of characters used to represent text. Strings are immutable, meaning their content cannot be changed after creation. They can be created as primitives (preferred) or as objects using the String constructor.

    Creating Strings

    Strings can be created using:

    • String Literals: Enclosed in single ('), double ("), or backticks (`) for template literals.

    let str1 = 'Hello'; // Single quotes
    let str2 = "World"; // Double quotes
    let str3 = `Hello, ${str2}!`; // Template literal
    Copied!

    • String Constructor: Creates a string object (not recommended due to potential issues in comparisons).

    let strObj = new String('Hello');
    Copied!

    Accessing Characters

    Characters in a string can be accessed using:

    • Bracket Notation:

    let char = "JavaScript"[4]; // 'S'
    Copied!

    • charAt() Method:

    let char = "JavaScript".charAt(4); // 'S'
    Copied!

    Common String Methods

    JavaScript provides numerous methods to manipulate strings:

    • Finding Length:

    let length = "JavaScript".length; // 10
    Copied!

    • Concatenation:

    let result = "Hello" + " " + "World"; // "Hello World"
    Copied!

    JavaScript strings are primitive values and are immutable. This means that modifying a string always results in a new string, leaving the original string unchanged. To create literal strings, you use either single quotes (') or double quotes (") like this: let greeting = "Hello"; Code language: JavaScript (javascript)
