Template Literals

In JavaScript template literals, expressions are embedded using the syntax ${ expression }. When the template literal is evaluated, any expressions inside the ${} placeholders are executed, and their results are converted to strings and included in the final string value. This feature, called string interpolation, greatly simplifies string concatenation compared to older methods like using the + operator. For example, `Hello, ${name}!` will replace ${name} with the value of the name variable. The expression can be any valid JavaScript expression, including variables, function calls, arithmetic operations, or even nested template literals.
