Intervals and Timers

Welcome to a new module in this course! I am super excited for this one, because now we're going to understand some important concepts in JavaScript. These concepts will later help us provide functionalities to our app like fetching data and sending data to servers. Until now, in this course, we have been dealing with something called synchronous JavaScript, and it's now time to understand asynchronous JavaScript . You might not understand these terms yet, but by the end of this lecture, you will know what they are and why these concepts are crucial to building real-world apps. So, let's get started! In this lesson, you'll learn about asynchronous JavaScript , a crucial concept for building responsive and efficient applications. Asynchronous JavaScript allows you to perform tasks like fetching data from a server or handling user interactions without blocking the execution of other code. ### Introduction to Asynchronous JavaScript JavaScript provides several built-in functions that enable you to execute code at specified intervals or after a delay, even while other code is running. This is particularly useful in scenarios like updating a game screen or tracking time on a website.

The rest of this lesson is waiting.
