What function do scripting languages perform in web development?

1. Creating animation and video that can be compressed

2. Developing applications in high-speed arcade graphics

3. Checking the accuracy of user-entered information on Web pages

4. Laying out or formatting Web pages

The correct answer is: Checking the accuracy of user-entered information on Web pages

Scripting languages play a crucial role in web development, particularly in enhancing user interaction and improving the functionality of web applications. The correct answer pertains to the function of validating user input which is essential for ensuring data integrity and enhancing user experience.

Additionally, scripting languages enhance user experience by providing immediate feedback to users, which makes the interaction smoother and more intuitive. This is critical for web applications where user input is a vital component, making the focus on validating this input paramount for effective web development. In contrast, while creating animations, developing graphics-rich applications, or formatting web pages are important aspects of web development, they are typically handled by different technologies or tools, such as CSS for layout and animation, or other programming languages for high-performance graphics. Thus, their focus is not
