Description: An asynchronous operation is a task that runs independently of the main flow of the program. This means that instead of blocking the execution of the program while waiting for a task to complete, such as a database query or an API call, the asynchronous operation allows the program to continue running. This approach is fundamental in modern application development as it enhances efficiency and user experience. Asynchronous operations are particularly useful for handling multiple data requests simultaneously, thus optimizing application performance. Operations can be queries, mutations, or subscriptions, and are managed through promises or callbacks, allowing developers to handle results once they are available without interrupting the application’s flow. Asynchronicity has become essential in the context of web and mobile applications, where speed and responsiveness are crucial to keeping users engaged and satisfied.
