JavaScript is commonly used for web development due to its role as the primary scripting language for creating dynamic and interactive web pages. It runs directly in the user's browser, allowing developers to manipulate HTML and CSS, respond to user events, and perform asynchronous operations. This interactivity is essential for modern web applications, enabling features such as form validation, animations, and real-time updates without needing to refresh the entire page.

While Python is also used in web development, particularly on the server side with frameworks like Django and Flask, JavaScript remains the standard for client-side scripting. Assembly language and C, although powerful for system-level programming and performance-critical applications, are not typically used for web development because they lack the direct functionality and ease of use that JavaScript provides in the context of web browsers.
