Utilizing template literals within the alert() function
Template literals allow embedding expressions within backticks. This approach utilizes template literals to include the variable directly within the alert() function, providing a cleaner and more readable way to display variable values.
Syntax:
alert(`Variable value: ${variable}`);
Example: Consider a variable age with a value of 30. We can use template literals to directly embed the variable value within a message displayed in the alert box.
let age = 22;
alert(`Age: ${age}`);
