Synchronous and asynchronous
Before diving into code, it’s important to understand the fundamental difference between synchronous and asynchronous execution. In synchronous programming, tasks are performed one after another, and each step waits for the previous one to complete. In contrast, asynchronous programming allows tasks to run independently or in parallel, enabling a program to remain responsive while waiting for slower operations, such as network or database calls.
In this section, we’ll explore these concepts through practical Kotlin examples. We’ll see how Kotlin handles both synchronous and asynchronous execution.
What is synchronous programming?
Synchronous programming is very easy to describe. It is the execution of instructions or tasks in a sequential manner, that is, we start at the beginning and finish at the end.
Let’s imagine that we have three tasks:
- Task A
 - Task B
 - Task C
