CODE A BOT IN VISUAL STUDIO FOR MAC CODE
This code saves a task’s state, starts running another synchronous or asynchronous function, and retrieves the saved task’s value when it’s actually needed. To do this, we modified our code to include a new function called PassTheTime. This is where asynchronous code comes in handy! By making our existing code asynchronous, we can perform more actions to pass the time even while we are awaiting a task like baking the cake in the oven to complete. Doing this increases your productivity and allows you to bake the cake much faster. In real life, you typically want to multitask by making the batter while the oven preheats or making the icing while the cake is baking.
You could be making the batter for your cake in the meantime! In other words, you will be standing completely still while waiting for the oven to finish preheating. However, since all the code is synchronous, each line will run sequentially. This code is serviceable, and you will still have a yummy cake once the method is done executing. This action will be represented by a thread that is executing several steps (or tasks), as illustrated in code below. To use an analogy to demonstrate async programming, consider the action of baking a cake.
Why should I use async code? Example please! Conversely, you can also have a multi-threaded async application, where multiple threads can each run multiple concurrent tasks. This means you can have a single-threaded async program, where one thread can run concurrent tasks. In reality, async programming can be used together with singular or multithreaded applications. After all, many methods could be executing at the same time in both. You may think async code seems a little like multithreaded code. Instead, the major perk of async programming is that it increases the number of tasks ( throughput) that can be executed concurrently without having to block the thread where these actions are taking place. A common myth about async code is that it improves performance, which isn’t necessarily true. Whether you’re new to it or you just want a refresher, here is an intro to the world of asynchronous code!Īsynchronous (async) programming lets you execute a block of code without stopping (or blocking) the entire thread where the action is being executed.
As a result, understanding how this code even works can be tough no matter your experience level. Unfortunately, asynchronous programming adds an additional level of complexity to your code. Increasingly essential to writing responsive applications, asynchronous code is becoming more and more popular.
