It looks something like this (remember that code just above?): 👇 Illustration of Callback hell You can store the ingredients inside objects like this: 👇 let stocks = as toppings`) Now, we're gonna store our ingredients inside an object.
We'll produce ice cream in our kitchen. The storeroom will have all the ingredients. To explain that in more detail, let's start our ice cream shop business. You can't just chop the fruit and serve ice cream.Īt the same time, if a previous step is not completed, we can't move on to the next step. Also note that in this example, the order of the steps and timing are crucial. These are the small steps you need to take to make ice cream. Take a look at this example:👇 Chart contains steps to make ice cream 
To help us establish a relationship between these steps according to time (optional) and order, we use callbacks. When doing a complex task, we break that task down into smaller steps. Here's an illustration of a callback: An example of a callbackÄon't worry, we'll see some examples of callbacks in a minute.
When you nest a function inside another function as an argument, that's called a callback. We'll write our code and see the results in the console. Open the JavaScript section, and then open your developer console. Or, you can do it in VS code or the editor of your choice.

How to Setup our ProjectÄŻor this project you can just open Codepen.io and start coding.
Now that you know the difference between synchronous and async operations, let's build our ice cream shop. Note: Don't worry, we'll discuss the setTimeout() function later in this article. Now, let's test out an asynchronous system. Let's say it takes two seconds to eat some ice cream. Here's the result in the console: 👇 Asynchronous code example To test a synchronous system, write this code in JavaScript: console.log(" I ") Synchronous and Asynchronous Code Examplesīefore starting our project, let's look at some examples and clear up any doubts. They'll finish the race on their own pace.
Asynchronous system, the three images are in different lanes. If image number 2 stops, the following image stops. Synchronous system, three images are in the same lane. When three images are on a marathon, in a: To Summarize Synchronous vs Asynchronous JS: None of them is waiting for any of the others. Take a look at the GIF 👇 – you can see that each image loads at the same time.Īgain, all the images are loading at their own pace. So, each hand can do each task independently and at the same time. Here, imagine that for 10 tasks, you have 10 hands. In this system, tasks are completed independently. Think about it like this – one thread means one hand with which to do stuff. Well, JavaScript is by default Synchronous. You'll see that until the first image is loaded completely, the second image doesn't start loading. Take a look at the GIF 👇 – one thing is happening at a time here: So, you have to complete one task at a time. Think of this as if you have just one hand to accomplish 10 tasks. In a synchronous system, tasks are completed one after another. Let's dive in!🎖️ Synchronous vs Asynchronous JavaScript What is a Synchronous System? Then you can use any of these three techniques – callbacks, promises or Async/await – to run those small tasks in a way that you get the best results. The theory of async JavaScript helps you break down big complex projects into smaller tasks. If you want to build projects efficiently, then this concept is for you. So let's dive in! You can watch this tutorial on YouTube as well if you like: What is Asynchronous JavaScript? Today we're going to build and run an ice cream shop and learn asynchronous JavaScript at the same time.
