Question

Select an appropriate use of JavaScript:

a) Sending e-mail
b) None of these
c) Form validation
d) Both, form validation and sending email

Answer 1

JavaScript is correctly utilized for form validation on the client side, ensuring data is in the proper format before it is sent to a server. While it can be involved in email processes, it does not directly send emails, as this requires server-side processing.

Step-by-step explanation:

When selecting an appropriate use of JavaScript, option c) Form validation is correct. JavaScript is commonly used for verifying that the information entered into a web form is in the correct format before it is sent to a server. This includes tasks such as checking that all required fields are filled out, the email address is in a valid format, or that passwords meet certain strength requirements. While option d) mentions both form validation and sending email, JavaScript on the client side is not typically used for sending emails directly, as this process generally requires a server-side language to interact with mail servers for security and reliability reasons. Therefore, option d) is not as appropriate as option c).
