What are some examples of synchronous code?

Synchronous code executes sequentially, meaning each operation must complete before the next one starts. For example, in JavaScript, a simple synchronous function could look like this:

function add(a, b) {
    return a + b;
}

console.log(add(2, 3)); // Outputs: 5

Can you give me another example in Python?

Sure! Here's a synchronous example in Python:

def multiply(x, y):
    return x * y

result = multiply(4, 5)
print(result)  # Outputs: 20

What about synchronous code in Java?

In Java, a synchronous example would be:

public class Main {
    public static void main(String[] args) {
        int sum = add(5, 10);
        System.out.println(sum); // Outputs: 15
    }

    public static int add(int a, int b) {
        return a + b;
    }
}

How does synchronous code differ from asynchronous code?

Synchronous code blocks the execution until the current operation completes, while asynchronous code allows other operations to run concurrently, improving efficiency in tasks like I/O operations.
