Q
How can you include variable values in an alert message using window.alert()?

Answer & Solution

Answer: Option Option A
Solution:
Variable values can be included in an alert message using window.alert() by concatenating variables with the message string. For example, var name = 'John'; window.alert('Hello, ' + name); will display 'Hello, John' in the alert dialog box. The variables are concatenated within the string using the + operator to form the complete message. Using special placeholder syntax or assigning variables directly to the alert method is not valid syntax for including variable values in an alert message.
