Asynchronous JavaScript enables tasks to run without blocking the execution of other code, making it crucial for creating efficient, responsive web applications. Unlike synchronous programming, where tasks are executed sequentially, asynchronous programming allows operations like data fetching or file processing to run in the background while the rest of the code continues executing. This ensures a smooth user experience, especially in apps handling time-consuming tasks. JavaScript uses callbacks, promises, and async/await to manage asynchronous operations, improving performance and scalabili

In Java, the Throwable class is the superclass of all exceptions and errors. While it might seem convenient to catch Throwable to handle every possible issue, doing so is generally discouraged. Catching Throwable is only appropriate in specific cases like final resource cleanup, top-level error handling, or when building frameworks that must manage all potential errors. However, overusing this approach can mask serious issues, such as OutOfMemoryError, that should be handled differently. For a more in-depth guide on how to properly manage exceptions in Java, refer to this Java Exception Handl
