    String interpolation is a feature in JavaScript that allows you to embed variables, function calls, and expressions directly within a string. This feature was introduced in ES6 and is implemented using template literals, which are enclosed by backticks (``) instead of single or double quotes.

    Template Literals

    Template literals provide a more readable and convenient way to create strings, especially when dealing with multi-line strings or embedding expressions. The syntax for embedding expressions within a template literal is ${expression}.

    Example

    const name = "Alice";
    const greeting = `Hello, ${name}!`;
    console.log(greeting); // Output: Hello, Alice!
    Copied!

    In this example, the variable name is embedded within the string using ${name}. The resulting string is "Hello, Alice!".

    Multi-line Strings

    Template literals also allow for multi-line strings without the need for escape characters. This makes the code more readable and easier to maintain.
