Create dynamic strings with embedded expressions and multi-line support.
Template literals (or template strings) are a significant quality-of-life improvement introduced in ES6 for working with strings. They are enclosed by backticks (``) instead of single or double quotes. Their main advantage is the ability to embed expressions directly into the string using the `${expression}` syntax. The expression inside the curly braces is evaluated, and its result is included in the string. This is far cleaner and more readable than traditional string concatenation using the `+` operator, especially when combining multiple variables and static text. Another major benefit is native support for multi-line strings. With traditional strings, creating a multi-line string required using the newline character `\n` or string concatenation, which was clumsy. With template literals, you can simply press enter and write your text on a new line, and the whitespace and line breaks will be preserved in the final string. This is particularly useful for creating HTML templates, formatted text blocks, or any string that spans multiple lines. Template literals make string manipulation in JavaScript more intuitive, powerful, and less error-prone.
