Synchronous vs Asynchronous API with Examples

Описание: Synchronous vs Asynchronous API with Examples

Synchronous API:
In a synchronous API, each operation is executed sequentially. The program waits for a task to be completed before moving on to the next one. This creates a blocking flow where the execution is paused until a task is finished.

Characteristics:
Blocking: Each call must finish before the next one starts.
Sequential: Tasks are performed in a strict order.
Slower for I/O operations: If one task takes time (e.g., fetching data from a server), the whole system waits.

Asynchronous API:
In an asynchronous API, tasks are initiated but the program does not wait for them to finish. The program continues executing the next instructions while the asynchronous task works in the background. This is non-blocking and allows for more efficient multitasking.

Characteristics:
Non-blocking: The program continues to run without waiting for a task to finish.
Concurrent execution: Multiple tasks can run at the same time.
Ideal for I/O operations: Fetching data, database queries, and file operations can occur without freezing the system.
