Javascript Programming Tutorials, Guides & Best Practices

In this example, the processData function is asynchronous, and await is used to wait for the fetchData Promise to resolve before continuing. The code is easier to read and reason about compared to a chain of then methods.

Error handling with async/await is done using try/catch blocks. If a Promise is rejected, the code inside the catch block will execute.

JavaScript patterns are reusable solutions to common problems in software design. By following these patterns, you can improve the structure of your code, make it more predictable, and reduce the likelihood of bugs. In this tutorial, we'll cover some of the most important patterns that every JavaScript developer should know.

The Module Pattern is one of the most common design patterns in JavaScript. It allows you to encapsulate private and public variables and methods, providing a clean and organized way to manage your code.
