Which statement about JavaScript is true regarding its usage?

• A. It can only run on servers
• B. It has no syntax for comments
• C. It was primarily used for manipulating webpage elements
• D. It can replace Java in server applications

Answer: (C)

The statement emphasizing that JavaScript was primarily used for manipulating webpage elements is accurate, as this reflects the foundational role that JavaScript plays in web development. Initially designed to enhance user interaction on web pages, JavaScript allows developers to dynamically manipulate HTML content, respond to user events, and create rich, interactive experiences in browsers. Over time, while its use has expanded significantly to include server-side programming (with technologies like Node.js), its initial purpose was to make web pages more interactive and engaging.

The other statements do not convey true information about JavaScript. For instance, JavaScript can run both on clients (browsers) and servers. It does indeed have well-defined syntax for comments, enabling developers to add descriptions and notes within their code. Additionally, while JavaScript can be used in server applications, it does not serve as a replacement for Java, which is a completely different programming language with its own distinct features and use cases.
