Template Literals
Template literals are a JavaScript language feature introduced in ES6 (ECMAScript 2015) that provide an enhanced way to work with strings. They use backticks (`) instead of quotes and allow for multi-line strings, string interpolation with embedded expressions, and tagged templates for custom string processing. This feature simplifies string concatenation and improves code readability in JavaScript applications.
Developers should use template literals whenever they need to create dynamic strings with variables or expressions, especially for generating HTML, SQL queries, or formatted messages. They are essential for modern JavaScript development as they eliminate the need for cumbersome string concatenation with the + operator and make code more maintainable, particularly in frameworks like React for JSX-like syntax or in Node.js for building templates.
