What are some examples of synchronous code in programming?

What are some examples of synchronous code in programming?

Synchronous code executes sequentially, meaning each operation must complete before the next one starts. Examples include simple loops and function calls.

Can you give me a specific example in JavaScript?

Sure! Here's a simple example in JavaScript:

function fetchData() {
    const data = getDataFromAPI(); // This is a synchronous call
    console.log(data);
}
fetchData();

What happens if the API call takes a long time?

If the API call takes a long time, the entire program will wait and be unresponsive until the data is returned, which can lead to a poor user experience.

How can I avoid blocking the main thread?

You can use asynchronous programming techniques, such as callbacks, promises, or async/await, to avoid blocking the main thread.
