			// Template Literal Tests
			// Testing backtick (`) strings and ${} interpolation
			//
			// This test suite validates the template literal functionality including:
			// - Basic template literals with backticks
			// - Variable interpolation with ${}
			// - Expression evaluation within templates
			// - Multiple and consecutive interpolations
			// - Type conversion (numbers, booleans, objects)
			// - Multiline strings
			// - Escape sequences
			// - Complex expressions and nested calculations
			// - Integration with functions and methods
			// - Edge cases (empty, null, undefined)
			// - Practical use cases (URLs, receipts, error messages)
