Explanation:

JavaScript is a client-side scripting language, meaning that it executes in the user’s browser rather than on the server. This helps:

• Reduce server load by handling computations, form validations, and user interactions locally.
• Minimize storage requirements on the web server since many tasks can be performed on the client-side without frequent server requests.

Why the other options are incorrect:

• (A) make computations in HTML simpler → JavaScript enhances interactivity but does not directly simplify computations in HTML (though it can manipulate HTML dynamically).
• (C) increase the download time for the client → JavaScript files are usually lightweight and cached by browsers, so they do not necessarily increase download time.
• (D) none of the mentioned → Option (B) is correct, so this is incorrect.
