Template Literals
Template literals are a JavaScript language feature introduced in ES6 that allow for easier string interpolation and multi-line strings. They use backticks (`) instead of quotes and can embed expressions using ${expression} syntax, making string construction more readable and flexible. This feature also supports tagged templates for advanced string processing.
Developers should use template literals when building dynamic strings, such as generating HTML, constructing URLs, or creating formatted messages, as they improve code clarity and reduce concatenation errors. They are essential in modern JavaScript development for tasks like UI rendering, logging, and data formatting, especially in frameworks like React or Node.js where dynamic content is common.
