Javascript Programming Tutorials, Guides & Best Practices

function logError(error) {
    // Custom logging logic, e.g., send to a logging server
    console.error('Logged error:', error);
}

window.addEventListener('error', (event) => {
    logError(event.error);
});

window.addEventListener('unhandledrejection', (event) => {
    logError(event.reason);
});

By logging errors, you can gain insights into issues that users encounter, allowing you to prioritize and address them more effectively.

Example with Async/Await:

async function fetchData() {
    console.log("Start");

    const message = await new Promise((resolve) => {
        setTimeout(() => {
            resolve("Data fetched");
        }, 2000);
    });

    console.log(message);
    console.log("End");
}

fetchData();
