Which ES6 feature enables embedding expressions inside string literals using backticks?

• A. Destructuring
• B. Generators
• C. Template literals
• D. Modules

Answer: (C)

Template literals are the ES6 feature that lets you embed expressions inside string literals using backticks. By writing strings with backticks, you can place expressions inside ${ ... } and have them evaluated and inserted into the string, for example: Hello, ${name}! or 2 + 2 = ${2 + 2}. This also makes multi-line strings easy, without needing escapes.

Destructuring pulls values out of arrays or objects, Generators create iterators with yield, and Modules handle importing and exporting code. None of these provide the ability to interpolate expressions inside strings using backticks, which is unique to template literals.
