Sharding helps distribute the workload and allows for parallel processing of queries.
It improves performanc...
A callback is a function that is passed as an argument to another function and is executed later when a certain event occurs.
Callbacks are commonly used in asynchronous programming to handle the completion of a task.
They allow for the separation of concerns and promote code reusability.
An example is the use of callbacks in JavaScript's setTimeout() function.
Event loop is a mechanism that allows for efficient handling of multiple events in a single thread.
Event loop is used in asynchronous programming to handle non-blocking I/O operations.
It continuously checks for events in a queue and executes their associated callbacks.
Event loop is commonly used in JavaScript for handling browser events and asynchronous tasks.
It helps prevent blocking of the main thread and ensures res
